Pittsburgh Steelers quarterback Mason Rudolph was briefly hospitalized after being knocked unconscious by a vicious blow to the head during a game Sunday against the Baltimore Ravens.

Rudolph, who took over as the Steelers' signal-caller when Ben Roethlisberger suffered a season-ending injury in week three against Seattle, took the blow from Ravens safety Earl Thomas in the latter half of the third quarter. The hit knocked Rudolph out cold and left some of his Steelers teammates emotional as he lay motionless on the field.

“When he was on the ground, it looked like it was a lot more serious than just a simple hit,” Steelers offensive lineman Alejandro Villanueva said after the game, according to ESPN. “I don't like to get into details of his medical condition. You could tell he had been hit to the head and the only thing I could do was to wave the trainers down to the location.”

Thomas told reporters he didn’t “intentionally try to hurt" Rudolph.

“I'm worried about him,” Thomas said, according to ESPN. “I heard he's at the hospital. My prayers go out to him and his family. I've never tried to hurt anybody. At the end of the day, guys have families.”

Thomas didn't receive a penalty on the play.

Medical personnel took Rudolph’s facemask off and had to walk him off the field because the medical cart appeared to break down.

“Embarrassing,” the NFL Players’ Association executive director of external affairs George Atallah tweeted. “I guess $15 billion (estimated league revenue in 2018) a year can’t buy you a working medical cart.”
