Practice report: Sanchez rides bike

FLORHAM PARK, N.J. -- Jets quarterback Mark Sanchez did not participate in the early portion of practice on Monday, two days after suffering a right shoulder injury.

Sanchez was in uniform and wearing the traditional red jersey, but rode an exercise bike on the side while Geno Smith and Matt Simms took snaps during the portion of practice open to the media.

Sanchez was hurt in the fourth quarter of the Jets-Giants preseason game Saturday, when he was drilled by Giants defensive tackle Marvin Austin. He is officially listed as day-to-day by the team, but he will not play in the Jets' preseason finale against the Eagles on Thursday, and his availability for the regular season opener is in doubt, sources told ESPNNewYork.com's Rich Cimini.

The team has been vague about Sanchez's injury, calling it an "injured right shoulder," but sources have told ESPN NFL Insider Adam Schefter that an MRI revealed Sanchez has a bruised right shoulder joint. It should be noted that while Sanchez was riding the bike, he had his left hand on the handle while his right arm was to his side.

Many people have questioned coach Rex Ryan's decision to play Sanchez in the fourth quarter when it was clear he would be the team's Week 1 starter. Sanchez all but locked that job up after Smith threw three first-half interceptions and stepped out of bounds in the end zone for a safety in the Jets' win over the Giants.

Ryan angrily defended his decision to play Sanchez. He will address the media again this afternoon.

In other news, wideout Santonio Holmes practiced for the first time since being taken off the physically unable to perform list Friday. He had been out for 10 months following foot surgery.

Offensive lineman Vladimir Ducasse (leg) also practiced with the first team, as did defensive lineman Sheldon Richardson, who suffered an undisclosed injury Saturday.

Cornerbacks Antonio Cromartie (hip) and Dee Milliner (calf), and defensive lineman Kenrick Ellis (back), also did not practice.
