The Browns got off to a hot start, but now have what could be a serious problem.
Quarterback Baker Mayfield has just headed to the locker room with Browns medical personnel.
Mayfield appeared to come up wincing after a run, and a few plays later, he dropped to one knee after a throw, in apparent pain.
Mayfield came back out after a few minutes, so he may be well enough to return.
Garrett Gilbert is the Browns backup and only other quarterback on the roster at the moment.
The situation makes worse a bit of a rough spot for their offense, which got out to a 20-6 lead but then turned the ball over on three of their last four possessions, including a pair of interceptions by Mayfield.
That’s allowed the Seahawks to come back to take a 25-20 lead.
