Steelers quarterback Mason Rudolph had to be helped off of the field by teammates in the third quarter against the Ravens after a scary hit from Earl Thomas. He will not return to the game after being diagnosed with a concussion.

No flag was issued on the play initially, although there was some helmet-to-helmet contact and Rudolph can be seen going limp in mid-air as he falls to the ground. He remained down for several minutes before being assisted off the field; an issue with the medical cart reportedly prevented Rudolph from being carted off.
