The Green Bay Packers lost receivers Randall Cobb and James Jones to leg injuries in the first half at Baltimore on Sunday.
Jones appeared to hurt his left knee on a pass play in the first quarter. He limped off the field and the Packers called it a ``leg injury''.
Cobb, the team's best breakaway threat at the position, was injured when he was struck in the right leg on a tackle by safety Matt Elam near the end of the half.
Houston quarterback Matt Schaub left against the St. Louis Rams in the third quarter with an apparent right ankle injury. Schaub was injured when he was sacked by Chris Long late in the third quarter. He remained on the turf for a few minutes before trainers helped him as he hobbled off the field.
Texans coach Gary Kubiak didn't have many details on Schaub's injury after the game, saying only: ``Matt's got a little bit of everything on that one leg.''
Houston WR Keshawn Martin injured a shoulder and safety Danieal Manning damaged his right knee.
Cardinals defensive end Calais Campbell was carted off the field at San Francisco with an apparent right leg injury. Campbell was hurt when his leg buckled beneath him as he helped bring down Frank Gore on a 1-yard gain late in the game.
