Redskins linebacker Brian Orakpo also could be out a significant portion of time after re-injuring the shoulder/pectoral muscle that required surgery earlier this year. Orakpo is expected to visit Dr. James Andrews. That's never a good sign.
Here's are the rest of the Week 2 injuries you need to know:
1. The New York Giants lost two offensive starters. Left tackle David Diehl left with a knee injury. The team is hopeful it's not too serious, according to USA Today. Running back Ahmad Bradshaw underwent an X-ray for a neck injury. His status remains unclear. Wide receiver Domenik Hixon also left with a concussion.
2. The injuries came in bunches for NFC East teams. Philadelphia Eagles center Jason Kelce, left tackle King Dunlap and wide receiver Jeremy Maclin were all hurt during a win over the Baltimore Ravens. Kelce's injury appeared to be the most serious.
3. The New England Patriots' famed two-tight end offense might take a break for a while. Aaron Hernandez's ankle isn't broken, according to NFL Network and NFL.com reporter Albert Breer. But it sure looked like a serious sprain that could keep Hernandez on the sideline. (And get wide receiver Wes Welker on the field more.)
4. St. Louis Rams coach Jeff Fisher said Steven Jackson suffered a groin injury Sunday before he was removed from the game. Whether Jackson actually was hurt or just benched remains somewhat mysterious.
6. Jacksonville Jaguars quarterback Blaine Gabbert will undergo an MRI on his toe and hamstring, according to ProFootballTalk.com. Chad Henne replaced Gabbert late in the Jaguars' loss to the Houston Texans.
9. Seattle Seahawks wide receiver Sidney Rice wasn't listed on the postgame injury report, but he was taken out of the game early. Odd. It seems like the Seahawks were resting him in a comfortable win, but we'd keep an eye on his practice availability. Rice hasn't looked right this season.Follow Gregg Rosenthal on Twitter @greggrosenthal.
