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.
"Nobody cares about our problems," Steelers coach Mike Tomlin said. "They're glad we've got them. We need to understand that. We need to stick together and persevere.
The Giants and Cowboys each lost a prominent cornerback during their Sunday night showdown. New York's Prince Amukamara sustained a concussion in the first half and Morris Claiborne of Dallas was forced out in the third quarter with a shoulder problem. Claiborne later returned to the game.
Kansas City running back Jamaal Charles and Jacksonville quarterback Blaine Gabbert each departed the Chiefs' 28-2 victory due to injuries.
Charles left in the third — after getting sandwiched by linebackers Geno Hayes and Paul Posluszny — and returned for two carries before calling it a day in the fourth. He had 77 yards and a touchdown on 16 carries before the quadriceps injury.
"He did go back in for a play after he got stepped on, then we pulled him out," Kansas City coach Andy Reid said. "It was a quad and you don't mess with those. I think he's going to be OK."
Gabbert cut the back of his right hand on a defender's facemask in the closing minutes 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.
