Stoke City boss Mark Hughes is hopeful that Marko Arnautovic’s injury is not serious, but Charlie Adam is facing “a few weeks” on the sidelines.
Arnautovic scored Stoke’s goal in their 1-0 win at Liverpool on Tuesday night but had to be withdrawn towards the second half of normal time after taking a blow to his back.
Adam, meanwhile, limped off with a calf injury in the first half of extra-time having earlier come on as a substitute himself.
Both players would likely have taken spot-kicks in the shootout had they still been on the pitch, with Peter Crouch and Marc Muniesa’s misses proving costly as City missed out on a trip to Wembley.
Hughes told The Sentinel of the injuries: “Charlie has popped his calf and he felt quite a bit of pain. It’ll be a few weeks I think.
“Marko has got a couple of bangs in his back which he’s been struggling with for a couple of weeks. Hopefully that will settle down and he’ll be ok.”
Stoke, who are also set to be without Ryan Shawcross for up to a month, go to Crystal Palace in the fourth round of the FA Cup on Saturday before another away game at Manchester United next Tuesday.
