Injuries are a fact of life in the NFL. Who were among the players bit by the injury bug in Week 2? Find all the key ailments below.
• Andre Johnson: The Texans' wideout suffered a possible concussion late in the fourth quarter of Houston's 30-24 overtime victory against the Titans. He appeared to be injured after Titans safety Bernard Pollard hit him around his head after Johnson made a 21-yard catch to set up a game-tying score.
"He’s being evaluated as we speak," Texans coach Gary Kubiak said during a postgame news conference, according to NFL.com. "...I have no diagnosis yet."
The Houston Chronicle's John McClain reported that Johnson was not made available for postgame interviews due to the league’s concussion protocol.
• Ray Rice: Rice has been diagnosed with a hip flexor strain. The Ravens' star running back dropped to the turf late in the game without being tackled. He limped to the sideline under his own power but appeared to be in some pain. Coach John Harbaugh said after the Ravens' 14-6 win that Rice will not undergo an MRI.
• Reggie Bush: The Lions' running back was confined to the sideline after a left knee injury. He is scheduled to have an MRI on Monday. Chris Burke says the injury could cost Detroit much-needed firepower.
• Malcom Floyd: Floyd was carted off the field on a stretcher following a scary hit from the Eagles' DeMeco Ryans. A CT scan of Floyd's neck was negative, according to reports. "He's doing fine," Chargers coach Mike McCoy told reporters. "All the tests right now look good. It's great for the organization to go out and get a win for Malcom." Floyd joined his teammates on their flight home following a 33-30 win over the Eagles.
• Russell Okung: The Seahawks' offensive lineman left the Seattle-San Francisco tilt with a foot injury and did not return to the game.
• Eddie Lacy, Brandon Meriweather:
