Nottingham Forest head coach Steve Cooper has suggested Neco Williams suffered a nasty injury during the win over Brighton.
The defender was withdrawn in the second half, leaving the field on a stretcher following a collision with Brennan Johnson.
Williams received lengthy treatment on the field and then headed straight to the hospital for checks.

The Wales star was playing brilliantly and but for Johnson getting in his way, he might have scored for the second game running.
Williams was playing in a more advanced role last night and that does appear to suit him more.
Now, he could face some time out of action, however, with his injury not looking particularly great.
Cooper was quizzed on his player afterwards and it doesn’t appear that it looks too good for Williams.
The head coach told BT Sport: “Again, we’ve been unfortunate with a few injuries. Moussa has had to come off halfway through the first half, Neco, he’s just about to score I think and he comes off with a broken face or whatever it was. I’m sitting there thinking not again.
Williams signed for Forest from Liverpool for £17 million in the summer. He hasn’t always been the first choice, however, with Serge Aurier taking that mantle.
Last night Cooper chose to utilise both of his right-backs, with Aurier playing as a central defender and it worked a treat.
Cooper thinks Williams has picked up a nasty injury
It never rains it pours for the Reds these days. It seems as though the team are getting two or three injuries in every single game right now.
Forest desperately need some good news on Williams. He’s just starting to play well and his energy is very useful.

The player did look in some discomfort as he left the field on a stretcher.
Forest should know more on his injury in the coming days but with a short turnaround to Saturday’s game, they might have to prepare contingency plans.
At 21, Williams is a talented boy. He never shys away from hard work and he will be desperate to play on Saturday.
