Cooper had to be withdrawn in the 72nd minute of the clash with Blackburn with a knock. Scans have since shown he has a small tear in his groin.
The injury isn’t thought to be serious but it will mean that he misses the upcoming Scotland camp.
Leeds captain Cooper misses another Scotland camp
Cooper’s been part of a Leeds squad who have performed well under Marcelo Bielsa’s squad over the past year. They are currently third in the Championship table.
He’s only made two appearance for the national team though. His debut came in the 2-1 defeat to Russia in September and his second followed shortly during a 4-0 defeat to Belgium.
It’s another camp he hasn’t made though since then. Last month he pulled out the squad again due to injury, missing matches against Russia and San Marino.
Injury has cost him the chance to make more Scotland appearances this time though and it’ll be interesting to see if Cooper’s absence opens up opportunities for the likes of Declan Gallagher and Mikey Devlin.
