The first Sunday of the NFL season was a costly one for the Pittsburgh Steelers.
Pro Bowl center Maurkice Pouncey ripped up his right knee and linebacker Larry Foote ruptured his biceps during Pittsburgh's 16-9 home loss to Tennessee, likely sidelining both players for the rest of the season.
Jacksonville quarterback Blaine Gabbert cut the back of his right hand on a defender's face mask in the closing minutes of a 28-2 loss to Kansas City and needed 15 stitches. He threw two interceptions while playing with a hairline fracture in his right thumb.
Carolina lost starting right guard Garry Williams to a left knee injury in the first quarter of a 12-7 loss to Seattle, and Detroit finished a 34-24 victory against Minnesota without Jason Fox after the offensive tackle departed with a groin injury.
