Bradford's hopes of League One survival have been hit by an injury to Kelly Youga.
The on-loan Charlton defender was forced out of Saturday's 2-0 defeat to Leyton Orient with a dead leg and scans have since revealed internal bleeding.
He will miss the final two games of the season as Bradford try to overturn a four-point deficit on nearest rivals Cheltenham.
"It looks like we've seen the last of Kelly," Bradford boss David Wetherall told the Telegraph & Argus.
"We've had the injury scanned and it doesn't look good.
"I'm pretty certain the timescale for recovery will be longer than two weeks."
Youga has made 11 appearances for The Bantams since arriving in late January and Wetherall admitted: "It's another blow for us because he has settled in well and done a great job."
Marc Bridge Wilkinson and on-loan Watford striker Moses Ashikodi both recently sustained injuries and will miss the end of the season.
"The last thing we need is to keep losing players who are very important to us," added Wetherall.
