Croatian midfielder Ante Suto is the latest recruit at Easter Road.
The 25-year-old joins from the top tier club Slaven Belupo in his homeland on a two-and-a-half year deal.
Suto is an attacking player and with Keiron Bowie now off to Italy, David Gray was keen to add to his strike force before the window closes.
And there may be more business to come at Hibernian before the 11.00pm deadline!
Before we go to Leith, let's check in on Tayside and specifically with Dundee United.
Specifically, there have been links to three players - former St Mirren winger Kyle McAllister, Walsall defender Evan Weir and Emmanuel Agyei.
The Ghanaian midfielder currently plies his trade at Ashdod in Israel.
The rumoured departure of Ivan Dolcek has been rumbling on all month, but there's still nothing solid yet. Julius Eskesen finds himself in the same boat.

Good news coming up shortly for Hibs fans...

It is worth keeping an eye on Dundee tonight.
And not just because I expect them to complete the loan signing of Mexican striker Francisco Valenzuela.
I would not be at all surprised if they further bolster their attacking options with a potentially eye-catching recruit.
It is very much a case of 'watch this space'.
Some exciting news coming from Dens Park now.
Tyrone Smith has more.

With David Martindale moving upstairs, it’s Marvin Bartley who is now in control of who comes in and who goes out.
And with the average of just one goal per game it’s a striker he is looking out for, to try and claw themselves out of trouble and away from the automatic relegation place.
We told you Livingston were done earlier. Not so.
Our intrepid reporter Brian McLauchlin has the latest...
Staying with Celtic, Arne Engels looks set to remain at Parkhead as the club reject a deal worth up to £25m from Nottingham Forest. Here's what the fans think...
Owen: Typical Celtic to turn down an amazing offer for a player who has done very little. If they didn't replace him, then that would be like for like.
John: Engels value is a joke. I don't think he's even worth what Celtic paid for him. Not consistent enough. Celtic should have taken Forest's hand off.
Walter: Celtic must be applauded for holding off an English club until the money or time is right to sell. English clubs like to think they can get players from Scotland on the cheap.
Owen: Engels is the best midfielder in the league. Too many 'Celtic da's' talking absolute nonsense saying he goes missing. A club would not bid such exorbitant amounts for a midfielder that goes missing. Often Celtic's best player on the pitch (especially on Europe). Selling him would be handing Hearts or Rangers the title.
Harry: Engels is a talented player who will further develop his career outside of Scotland. Celtic should accept the £25 million offer.
Celtic have announced the signing of Austria international Junior Adamu on loan until the end of the season, with an option to buy at the campaign's end.
The 24-year-old is a striker, who can play wide. We'll call him a forward, then.
He arrives from Freiburg and has made 29 appearances so far this season, including in the Europa League.
That's the third signing of the January window - all of them loans, so far.
Image source, SNSSome news coming in from Celtic Park, now...
Arrival incoming.
No more rumour arrivals for Kilmarnock, but plenty of chat about players going out the door.
Scott Tiffoney has been linked with his old club Morton, while there are reports Liam Polworth could be heading up north to Ross County.
Defenders George Stanger and Lewis Mayo are others attracting interest. The latter missed the 3-0 win over Aberdeen at the weekend with a small knock.
It seems Portsmouth might be in for Mayo, after the south coast club chased Dundee's Luke Graham - another centre-half.

We've not talked about Rangers yet.
The man they've been linked with heavily is Ryan Naderi, a striker from Hansa Rostock, who has now arrived for a medical.
The 22-year-old has eight goals this season and was initially expected to move in the summer, but their timeline has moved up.
Cameron Archer was another potential incoming, on loan from Southampton, but that move seems to be dead in the water.
There's plenty of rumoured outgoings as well - Joe Rothwell to Sheffield United, Danilo to NEC Nijmegen, Clinton Nsiala to Westerlo and Rabbi Matondo to join Philippe Clement at Norwich City.
All of those are allegedly just loans.

The lights are fading at Falkirk and it look as if they have completed their transfer business for this window with Ben Broggio the final new recruit in the door.
The 19-year-old is a former England youth player and has joined on loan from Aston Villa until the end of the season.
Image source, Getty ImagesAccording to reports from Sky Sports, Nottingham Forest have now cooled their interest in Arne Engels after being knocked back on three occasions.
It was a reported fee of £25m - £20m up front plus £5m in add-ons - that Celtic seemingly knocked back, with the reason being the Parkhead club couldn't find a replacement in time.
What do you think Celtic fans - happy with that news?
Image source, SNSAfter the Dennis Geiger signing, it might be a quiet evening in terms of arrivals to Pittodrie.
Manchester United youngster Tyler Fredricson had been linked, but the defender picked up an injury which scuppered any Old Trafford exit.
As for outgoings, midfielders Adil Aouchiche, Ante Palaversa and Leighton Clarkson have all been linked with exits.
Nothing confirmed as of yet.
Image source, SNSAdil Aouchiche has been linked with a move to Schalke
Elsewhere, there are plenty of Scots who could be looking for moving vans in the next few days.
Scotland captain Andy Robertson has been linked with a move to Tottenham, with international teammate Che Adams allegedly on his way to Wolves.
Ryan Hardie was knocking on the Scotland door 12 months ago. Those shouts have disappeared, as has his playing time, since moving to Wrexham. He might be on way back to Plymouth.
Young Scottish strikers are also in demand. Rory Wilson, the Under-21 cap at Aston Villa, has been linked with Bundesliga side Hoffenheim, while Bobby Wales has already moved Swansea to Huddersfield Town on loan.

At this early stage, it doesn't seem that likely. There is only one club who don't have rumours spreading about incomings and outgoings - Livingston.
But never rule anything out.

More on that arrival in Leith..
Hibs announce the signing of German wing-back Felix Passlack from Bochum a little earlier. The 27-year-old has signed a deal with the Easter Road club until June 2029.
Passlack, who plays on the right-hand side, was a former youth player at Borrusia Dortmund and, at the age of 17, became the youngest scorer in Champions League history when he scored against Legia Warsaw.
He was spotted in the stands against Rangers. I imagine he liked what he saw.
Image source, SNSWe're not just covering the Premiership, oh no. We love the Championship here at BBC Scotland, and there's been plenty of activity there, too.
Uche Ikpeazu has gone from the top of the league to the bottom, leaving St Johnstone to join Ross County permanently.
He's not the only one to jet away from Perthshire. Sven Sprangler has moved on loan to Newport County and youngster Jackson Mylchreest has been released.
Elsewhere, former Kilmarnock man Innes Cameron has joined Raith Rovers on loan from Barrow and Nikolay Todorov has moved from Arbroath to Queen's Park.
And over in Greenock, Morton have added defender Reuben Lopata-White on loan from Leeds United. They were in desperate need of some additions at the back.

The biggest bit of news Dundee fans want to hear is that star defender Luke Graham is going nowhere.
Unsurprisingly he has been at the centre of a whirl of speculation about his future, following a string of fine displays.
Despite reported interest from the likes of Portsmouth and QPR, I'm hearing he is staying put.
And that could well be the most important bit of business Dundee do during this window, such is his importance to Steven Pressley's side.
