Blades manager Kevin Blackwell said Henderson would give the his side added strength as they look to get back into the Premier League.

"Darius is someone I have tracked for a while and when Rob Hulse decided to go to Derby there was only one man in my mind that I wanted to replace him.

"He brings the quality of knowing how to win the division and I think that will be important.

"He knows how to play the game, he is a lad who knows about working for a living and I think that will help him fit into the Blades ethos."
