49ers cornerback Richard Sherman criticized Browns QB Baker Mayfield on Monday night after Mayfield reportedly didn't shake hands with San Francisco during the pregame coin toss.

"What's amazing, and annoying, was him not shaking hands at the beginning," Sherman said, according to the NFL Network's Michael Silver. "That's some college s---. It's ridiculous. We're all trying to get psyched up, but shaking hands with your opponent -- that's NFL etiquette. And when you pull bush league stuff, that's disrespectful to the game. And believe me, that's gonna get us fired up."

Sherman and the 49ers defense were certainly fired up on Monday following Mayfield's snub. San Francisco forced four turnovers in its 31-3 home victory, holding Mayfield to just eight completions and 100 yards passing.

""He hasn't earned anything in this league. How many games has he won?" Sherman added postgame. "He's acting like he was the MVP last year. If [Patrick] Mahomes did that, it would be one thing. But he would never do that, because he has too much respect for the game."

Video tweeted on Tuesday disputed Sherman's claim. Mayfield shook hands with 49ers tight end George Kittle and defensive lineman DeForest Buckner at midfield, and he had a brief shake with Sherman. San Francisco's cornerback responded to the video on Tuesday, noting the discrepancy in his handshake compared to those involving Buckner and Kittle

Mayfield tossed two interceptions on Monday, including one to Sherman in the first quarter. Sherman now has two interceptions in 2019 and 34 in his nine-year career.



San Francisco advanced to 4–0 with Monday's victory. The 49ers are the NFC's lone undefeated team before they travel to Los Angeles for a battle against the Rams on Sunday.

Mayfield leads the NFL with eight interceptions in five games. His 68.5 passer rating is the NFL's worst mark among the 28 quarterbacks with at least 100 pass attempts.

Cleveland sits second in the AFC North at 2–3 after Monday's loss. The Browns will host the Seahawks in Week 6.
