Browns quarterback Cody Kessler may not be available

Cleveland quarterback Cody Kessler has injuries to his ribs and chest and may not be available for this week’s game at Tennessee. The rookie from USC got hurt in the first half of Sunday’s loss to New England and was replaced by Charlie Whitehurst, who injured his left knee in the final minutes. He and Kessler are considered day to day.

The Browns have started three quarterbacks this season and played five in five games. Josh McCown, who broke his collarbone in Week 2, was cleared to practice.

Romo on mend

Dallas quarterback Tony Romo underwent an MRI exam on his back, but Cowboys Coach Jason Garrett said he did not have an update on the results when he met with reporters.

Team owner Jerry Jones had said Sunday after the Cowboys’ victory over Cincinnati that he anticipated good news on Romo and expected the MRI to show that the compression fracture the quarterback suffered in his lower back nearly seven weeks ago had fully healed.

But Garrett deflected questions about a possible quarterback controversy between Romo and rookie Dak Prescott, who has helped Dallas to a 4-1 start. The coach wasn’t ready to give a timeline for Romo’s return, and said it would be “a little bit further down the road” before Romo would be able to work his way into team drills on a limited basis. “You try to ramp him up each day as we go,” Garrett said.

Freak injury

The Miami Dolphins said rookie guard Laremy Tunsil missed Sunday’s game because he hurt his ankle when he slipped in the shower at the team hotel several hours before kickoff. “It’s like one of those one-in-a-thousand or one-in-a-million type deals,” Coach Adam Gase said.
