Wolverhampton Wanderers midfielder Karl Henry has undergone a scan to determine the extent of his hamstring injury.
The complaint forced the 29-year-old to limp out of his side's 5-0 defeat Fulham yesterday afternoon with just 19 minutes on the clock.
"We don't know how bad it is. We'll see what the scan shows," said interim manager Terry Connor. "Obviously it was bad enough for Karl to come off straight away. There's clearly some damage.
"Fingers crossed he'll be OK. Hopefully the injury was caught it in time and maybe we can get him back on the pitch sooner rather than later."
Henry had only just returned from a three-match suspension.
