The number of Week 7 injuries has been relatively low, but the status of some high-profile players remains uncertain. Perhaps the most notable is Detroit Lions quarterback Matthew Stafford, who was sacked seven times on Sunday. Stafford had X-rays on his left hand after a loss to the Minnesota Vikings, but said he thought it was fine.

Here are some other top players who are battling injuries and the latest news about their condition. 

Arian Foster, Houston Texans

In his fourth game back from groin surgery, Foster appeared to suffer a significant non-contact Achilles injury in the four quarter on Sunday. According to ESPN, doctors believe the Achilles tendon is torn, ending the Pro Bowler's season. Foster tallied 125 total yards and two touchdowns in garbage time after the Dolphins surged out to a 41-0 first-half lead before going down with the injury. He missed three games in 2014 and eight games in 2013 due to injury.

Jason Peters, Philadelphia Eagles

Philadelphia's All-Pro left tackle fell to the ground during the first quarter of Sunday night’s loss in Carolina and stayed there several minutes. Peters was carted off the field with what he Eagles would later call a lower back injury, and did not return. After the game, Peters said “I’ll be all right,” according to’s Reuben Frank. Peters said he plans to play in the Nov. 8 game against the Dallas Cowboys following the Eagles’ upcoming bye week.

Nick Mangold, New York Jets

The Pro-Bowl center appeared to have injured his neck in a collision with New England Patriots linebacker Jamie Collins in the final minute of the Jets' 30-21 defeat at Gillette Stadium. He walked off the field before being carted off to the locker room. According to ESPN’s Rich Cimini, Mangold had an X-ray and left the locker room wearing a neck brace. He has missed just three games in over nine NFL seasons.

Dez Bryant, Dallas Cowboys

Bryant sat out Dallas’ Week-7 loss, as he recovers from a foot injury he suffered on Sept. 13. According to NFL Insider Mike Garafolo, Bryant is 50/50 for next week’s game with Seattle, but the Cowboys are confident he will return for Week 9, when they host the Philadelphia Eagles. Quarterback Tony Romo is expected back for Week 11 against the Miami Dolphins.

Ben Roethlisberger, Pittsburgh Steelers

The 33-year-old did not play on Sunday despite practicing with a brace on his left knee throughout the week. Landry Jones made his first career start in his place and struggled in a 23-13 loss to the Kansas City Chiefs. Head coach Mike Tomlin told reporters after the game that he expects Roethlisberger to return in Week 8 when Pittsburgh hosts the undefeated Cincinnati Bengals. Roethlisberger hasn’t played since spraining his MCL in Week 3 against the St. Louis Rams, and the Steelers are 2-2 without him.
