Jets linebacker David Harris suffered a sprained AC joint in his shoulder during Sunday's loss to the Chargers, but an MRI revealed no structural damage, a source told Newsday.

Harris, an eight-year veteran and a mainstay in Rex Ryan's defense, was hurt while tackling running back Branden Oliver with 10:55 left in the game and did not return. Ryan, who called Harris "the most underrated player in the NFL" during the summer, noted in his postgame news conference that the linebacker rarely comes out of games. Harris is day-to-day.

In other injury news, cornerback Darrin Walls has a patellar tendon injury. "It happened after the first long pass of the game," Ryan said. "He played through it a little bit, but we'll see how it progresses through the week."

Quick return to Geno

This time Ryan didn't wait to name his starting quarterback for the week. "Well, I just realized after going through it last year what it put on our team," he said when asked about waiting a day to name Smith the starter after his Week 13 benching against the Dolphins in 2013. "But I think now it's let everybody know 'Geno's going to be the guy' and eliminate that distraction."

Keep it in locker room

What's the best way to prevent finger-pointing in the locker room? "Don't listen to you guys," linebacker Calvin Pace said, referring to the media. "At this point in time, only the people in the locker room matter. The media, the fans, they're not contributing to what's going on right now. We've got to fix this. I know we will. This is just about getting back to the basics and focusing on the task moving forward."
