EAST RUTHERFORD, N.J. -- It's now been a week since the setback that wasn't a setback, and New York Giants rookie wide receiver Odell Beckham still isn't practicing with the team. Obviously, this means the team's first-round draft pick won't play in Thursday's preseason finale against the Patriots, which means he won't have played in any of the Giants' five preseason games.

"He's not going to play," an obviously frustrated Giants coach Tom Coughlin said after Monday's practice, during which Beckham once again worked on a side field with the training staff. "Have you seen him practice? How about practicing first?"

Beckham's last full training camp practice was when he was still at LSU. He injured his hamstring in the first practice of Giants training camp July 22 and hasn't practiced in full with the team since. He returned to the field a bit a couple of weeks ago and was working his way into 11-on-11 drills, but then he hurt himself in practice again last Monday and hasn't practiced since.

"I think he's very frustrated," Coughlin said. "I think his whole personality's held in check because he's not able to do the things that he wants to do."

With Beckham out, the Giants have been using Jerrel Jernigan in his outside receiver spot. It's possible that preseason star Corey Washington could get a look there with the first team Thursday, but we thought that was possible last week and Washington didn't play until the fourth quarter against the Jets.

Obviously, Beckham's availability for the Sept. 8 "Monday Night Football" opener in Detroit is in serious doubt. The Giants don't like to rush rookies into action in the first place, and that's especially true when the rookie hasn't had a training camp.

In other Giants injury news:

• Guard Geoff Schwartz was seeing a foot specialist Monday to determine the severity of his toe injury. The Giants should have news on Schwartz at some point early this week, but it's safe to assume he'll have to miss at least the first few games of the regular season, if not many more.

• Guard Brandon Mosley missed a second straight day of practice due to a back injury and was getting examined by a doctor, according to Coughlin. John Jerry played with the first-team line in Mosley's right guard spot while rookie Weston Richburg manned Schwartz's left guard spot.

• Offensive lineman James Brewer remains out with a back injury, which could damage his chances of making the 53-man roster. Brewer was on the bubble to begin with.

• Return specialist Trindon Holliday also sat out of practice with a hamstring injury. Holliday did some individual work Sunday but did not appear to work at all Monday. With Holliday and Beckham both sidelined, the Giants are hurting at punt returner and may keep wide receiver Preston Parker because has experience in that role.
