Arca scored Boro's opening goal before being forced off

The 26-year-old Argentine was carried off during the first half of Saturday's 2-2 draw with Sunderland.

But strikers Tuncay Sanli and Mido, who were also injured during the game, have a chance of playing against Everton next Sunday.

"They went for scans but there's no significant damage," Southgate told the club's website.

Tuncay went off with a shin problem while Mido struggled with his hamstring before being taken off.

Jeremie Aliadiere is already out for a month with a hamstring problem.

Boro have a Carling Cup tie against Spurs on Wednesday, with their only fit striker, Dong-Gook Lee, having scored just once for the club.

But Southgate remained positive.

"We might have to play people in different positions or change formations or give young players a chance," added the Boro boss.

"We are having a fair amount thrown at us, but we roll our sleeves up and we take the challenge on."
