At least the Jets don’t have to worry about a significant injury to their star running back. Quarterback Sam Darnold may be out a while after being diagnosed with mononucleosis, but at least Le’Veon Bell won’t be joining him away from the team.

The Jets did get a scare from their big offseason addition, though. He was held out of practice Thursday with a sore shoulder and underwent an MRI exam. But a source confirmed there was no major damage or tears, as coach Adam Gase thought would be the case.

Bell was busy in his first game since the 2017 postseason, rushing 17 times for 60 yards and catching six passes for 32 yards and a touchdown in the Jets’ 17-16 loss to the Bills on Sunday.

Middle linebacker C.J. Mosley (groin) and defensive lineman Quinnen Williams (ankle), both hurt in the Bills game, missed practice for the second straight day. Left tackle Kelvin Beachum (ankle) and linebacker/defensive lineman John Franklin-Myers (foot) were also out. Offensive guard Brian Winters (shoulder), punt returner Braxton Berrios (hamstring) and defensive tackle Steve McLendon (ankle) were limited.

Ryan Kalil saw some positives for the offensive line after watching film of the season opener, just not nearly enough of them. The group couldn’t sustain quality play.

“I feel like at times we were a little bit out of control, trying to do too much, and then other times, playing a little slower than we probably needed to play,” the center said.

The group allowed four sacks and failed to open up holes for the running game, as the Jets averaged 3.2 yards per carry. Its struggles were understandable. The unit didn’t play together at all in the preseason and only had a few practices when everybody was active.

“That’s part of it,” Kalil said. “But that’s why now that we have all the pieces there, and we’re continuing to practice and work together, it will keep trending up.”

Safety Jamal Adams (hip) returned to practice Thursday on a limited basis. His absence Wednesday was the first time he missed a practice in his short NFL career, and he didn’t like how it felt.

“I was kind of upset about it,” he said. “It obviously happened. I didn’t plan for it to happen, but it did, and obviously I was back out there flying around and I’m ready to go.”
