"His back tightened up," Giants coach Tom Coughlin explained after practice. "He came out here ready to go, but then he couldn't."
As a result, John Jerry worked at right guard with the first-team offensive line while Weston Richburg, the most likely long-term replacement for Schwartz, worked at left guard. The Giants have major problems in this area, as detailed here earlier Sunday. Coughlin offered no insight on how long Mosley could be expected to be out.
Some other notes from Coughlin and Sunday's practice:
From the My God This Could Be Even Worse Than We Think Department: Coughlin was asked what he thought of left tackle Will Beatty's performance Friday and he said Beatty was working very hard every day in practice. Asked if he was happy with Beatty's work since returning from his injury, Coughlin said this: "'Happy' and 'satisfied' are not the words I would use to describe it, but I do recognize the progress and I do recognize that he's working hard at his trade." All righty, then.
Matter of fact, let's just keep profiling Coughlin quotes. This one on rookie wide receiver Odell Beckham Jr., who missed yet another practice with a hamstring injury: "I would like to see the young man practice before we start talking about him playing in the regular season. That would be a good thing."
Running back Peyton Hillis returned to practice after missing a couple of weeks with an ankle injury, and Coughlin described him as "rusty." Return man Trindon Holliday also did some work in punt return and individual drills but remains hobbled a bit by his own hamstring problems. Cornerback Prince Amukamara worked on the side with trainers as he continues to deal with a groin injury.
Yes, Ryan Nassib did work some at quarterback with the first-team offense in Sunday's practice. No, there's obviously no chance they're considering any kind of change. Nassib is certainly going to get a lot more work in Thursday night's preseason finale than Eli Manning is, and that's why he's practicing more this week. The third-teamers spent more time on the field Sunday than the first-teamers did for similar reasons.
