Just call him Scooter Leonhard

Injured S Jim Leonhard is out for the remainder of the season, but he's still working behind the scenes, trying to help his teammates prepare for games.

Leonhard, who broke his leg in a horrific practice collision two weeks ago, is helping the coaches break down game tape. Next week, the coaches may increase his workload, allowing him to make a game-plan presentation to the defensive backs.

Leonhard isn't getting around the Jets' practice facility on a motorized scooter with a vanity license plate. He has a Wisconsin tag (his home state), and the plate says, "Jim 36."

NEXT MAN UP: It's official: Dwight Lowery, a converted cornerback, will start at safety Sunday against the Pittsburgh Steelers. He will replace Eric Smith (concussion), who replaced Leonhard.

"Ultimately, I think his best position will be safety," defensive coordinator Mike Pettine said.

MONSTER IN THE MIDDLE: It was overshadowed by the loss and The Trip, but NT Sione Pouha played te best game of his career last Sunday against the Miami Dolphins. Pouha was credited with 10 tackles, one sack and one fumble recovery.

Pettine called the performance "as close to spectacular as he's going to get" -- and he meant that as a compliment. Pouha is a steady, blue-collar player, not a big-play machine. But he plays with "near flawless" technique, according to Pettine.

SCHOTT AT A WRITER: Offensive coordinator Brian Schottenheimer, in a light moment, said last season he carried around a New York Daily News clipping and used it as motivation late in the season. The headline of the article was, "Jets Need a Schott in the Arm." Can't imagine who would've written that.

THIS AND THAT: The Jets promoted DT Jarron Gilbert to their 53-man roster because another team was trying to sign him off their practice squad, according to Ryan ... DT Trevor Pryce (hip) is iffy for Sunday ... Rookie RB Joe McKnight has fresh legs and he's fast, making him an intriguing option this week. McKnight got two offensive snaps last week, and there's a "real possibility" he could have an expanded role against the Steelers, Ryan said ... QB Mark Sanchez is in the holiday spirit. He has a little singing Santa in his locker ...
