West Brom and Northern Ireland star Chris Brunt is a doubt for Euro 2016 after suffering a knee injury in Saturday's 3-2 win over Crystal Palace.
The 31-year-old suffered what may be a cruciate ligament injury when he fell awkwardly just before half-time.
Brunt, who was hit by a coin thrown by his own fans last week, has undergone a scan.
Baggies fans sang his name on 11 minutes against Palace in a show of support, and collected money for chosen charities.
Boss Tony Pulis said: "We're concerned about him. Looks as though he's done something to the knee joint.
Captain Darren Fletcher said: "We just hope that the scan proves that he's back for us soon and ready for Northern Ireland in the Euros as well.
"We care for our players and want them to do well for West Brom, but we think about other things as well. We'll wait and see with fingers crossed."
