Pittsburgh quarterback Mason Rudolph left Sunday's home game in the third quarter after suffering a concussion following a hit to the chin by Baltimore safety Earl Thomas.
Lined up in the shotgun, Rudolph scrambled to his left and flicked the ball to James Washington just before the crown of Thomas' helmet hit Rudolph under the chin. Rudolph limply fell to the ground and laid there with his eyes closed while medical personnel rushed to attend to him. Rudolph woozily made his way off the field and to a hospital for further evaluation.
"I was just flying to the ball like I normally do," Thomas said. "I was asking the ref what happened and they said upstairs said that a part of my helmet kind of hit him in the chin, and that's what caused the flag."
Rudolph eventually came to as trainers cut off his facemask. He needed to be helped off the field by teammates because the cart used to treat players stalled.
"Ask somebody that is in charge of that," coach Mike Tomlin said. "I don't drive carts and things of that nature."
• Chicago defensive tackle Akiem Hicks, who missed last week's game against the Vikings because of a knee injury, left in the first half against Oakland in London because of an elbow injury.
• Green Bay center Corey Linsley didn't return after leaving to be evaluated for a concussion at Dallas. Packers safety Darnell Savage suffered an ankle injury.
• Denver cornerback De'Vante Bausby was strapped to a backboard and taken off the field on a cart after colliding with teammate Alexander Johnson.
