Sunderland are waiting on the results of a scan to determine the extent of Duncan Watmore’s knee injury.
The England under-21 international, who has been in fine form of late, was stretchered off in the 83rd minute following a collision with Leicester City’s Christian Fuchs.
It came as another blow for David Moyes’ side who have already lost Paddy McNair and Lynden Gooch to long-term injuries, although Moyes did reveal that the latter doesn’t require surgery on an ankle injury.
“The team is getting better but, unfortunately, we’ve picked up another injury with Duncan.
“It doesn’t look great. Duncan has been playing well.”
He continued: “I’d love to say the two changes I made at half-time were tactical genius, but they were both enforced – Steven’s eye closed over and he had blurred vision and Jason felt ill.
“The good news is that he [Gooch] doesn’t need an operation. That’s the big news, his ankle will heal in time.
“But it’s still going to be an injury that keeps him out somewhere between eight and 12 weeks.”
