Terrell Suggs has confirmed that he has sustained a biceps tear during the Baltimore Ravens' loss to the Pittsburgh Steelers on Sunday.
However, the linebacker is optimistic that he will be able to continue playing for the Ravens.
Coach John Harbaugh told the Baltimore Sun: "We don't know the extent of it.
"It needs to be evaluated as far as coming back and possibly playing this week or not.
"I think we are encouraged that it may not be [long term]. We'll just have to see. If I knew that for sure, if I could say that for sure, I would. I just can't right now but we have some encouragement there."
The reigning NFL defensive player of the year was in his sixth game back from a torn Achilles.
