Manchester United striker Danny Welbeck is scheduled to have a scan on his knee today.
Welbeck, 18, came off in the second half at Oakwell after opening the scoring in the 2-0 victory over Barnsley in the Carling Cup.
Despite his night ending on a sour note, it could not dampen his delight at securing a place in the last eight of the competition.
Welbeck scored the winner against Wolves in the third round and was part of the United side that lifted the trophy last season when they defeated Tottenham.
He said: "It is great to get further in the cups. I'm already looking forward to the quarter-finals. We'll certainly enjoy it and do our best.
"We controlled the game against Barnsley in the second half. The youngsters did well and the experienced players in the team helped us massively."
Welbeck scored his fifth goal in 17 appearances for United in the fifth minute following a cross from Anderson.
The Manchester-born player added: "Anderson said he was going to hit it to the front post so I thought I could get it. The area was free so I drifted in and got my head onto it."Reuse content
