Tua Tagovailoa left Sunday’s Miami Dolphins game against the Buffalo Bills, a 35-0 loss, with what was later described as a rib injury.

Tests on Monday morning revealed that Tagovailoa had bruised ribs, but no major issues, Tom Pelissero of NFL Media reported. X-rays were negative. So it’ll be about pain tolerance and functionality moving forward, as the Dolphins get set to play the Las Vegas Raiders on the road this week.

Tagovailoa suffered a hit from Bills defensive end AJ Epenesa during Miami’s second drive of the game. On fourth-and-1, Epenesa connected with Tagovailoa as he threw a pass, which was incomplete, and Tagovailoa was slow to get up before trying to leave the field, and needed a couple of attempts just to get to the sideline. He was carted off.

It was a rough start all around for Tagovailoa, as he was sacked twice on a three-and-out opening possession.
