Manchester United goalkeeper Dean Henderson was forced off with a knock during Nottingham Forest's match against Barnsley.
Forest took on the Tykes in a pre-season friendly at Oakwell that finished with a goalless draw.
And it seems like manager Steve Cooper may have been dealt with an injury blow as Manchester United loanee Henderson limped out around the half-hour mark.
The goalkeeper didn't seem to have suffered a heavy injury but did look slightly uncomfortable taking a goal-kick a few minutes before his substitution.
The England international was replaced by fellow summer signing Wayne Hennessey before walking down the tunnel.
