Aston Villa midfielder Stephen Ireland suffered a suspected broken arm in defeat at Southampton.
Ireland added injury to insult by coming off in pain at half-time and was wearing a sling as Villa departed St Mary's.
"We need to have a look at him actually," said Villa boss Paul Lambert.
"It's his arm he's having a problem with at the minute. I don't know if it would be a fracture, that's the fear of it.
