RENTON, Wash. -- When the Seahawks signed Sidney Rice in the offseason to join Mike Williams as a linchpin in the receiving corps, the belief was that Seattle had found the missing ingredient in its passing game.
But both have been dogged by injuries, the latest being a concussion to Rice -- his second in less than a month -- that will keep him out of Thursday night's game against Philadelphia. Rice came up woozy after making a diving attempt for a pass across the middle in Sunday's 23-17 loss to Washington, a game in which both Rice and Williams were held without a reception.
Rice has 32 catches this season, although Thursday will be the third game he's missed. Williams has just 14 receptions, one touchdown and some harsh criticism for himself after Sunday's loss, when he had a key drop in the first half and was replaced later in the game by backup Ben Obomanu.
Williams has heard the talk that his drop-off this season is related to the big contract extension he was given at the end of his breakout season a year ago and that he doesn't have the same hunger anymore.
"I don't think there is any truth to that," Williams said.
A bigger concern for Seattle than Williams' lack of production might be Rice's health. He missed the first two games of the season with a labrum injury in his shoulder, and because the concussions happened within such a short span, he may be out longer this time.
Rice sustained a concussion against Baltimore, but was cleared to return the following week at St. Louis.
"I'm praying that he'll be OK with his head because those injuries can be very serious," quarterback Tarvaris Jackson said. "For him to have those back to back like that within a couple weeks, more importantly we're just more worried about his health than anything."
According to the Seattle Times, Seahawks coach Pete Carroll said Tuesday "there's not a helmet that he could put on his head that he could play this weekend."
Now, 11 games into their first season together, Rice and Williams have a combined 46 catches and just three touchdowns, and have failed to provide the impact for which the Seahawks had hoped.
On Tuesday, Williams said he wanted to be accountable for his struggles.
"When you're hard on yourself, the guys around you know you hold yourself accountable to how you're supposed to perform, how you're supposed to play," Williams said. "There is only one way to perform. Either you're making plays or you're not."
Last season, Williams was nearly the NFL's comeback player of the year. Given one more chance after being a first-round bust, Williams flourished when reunited in Seattle with Carroll, his former coach at USC.
Williams became the focal point of Seattle's passing game and, with a veteran quarterback in Matt Hasselbeck, had the best season of his career. Williams played in 14 games and caught 65 passes for 751 yards. He was rewarded at the end of the year with a three-year contract.
But now Hasselbeck is playing for Tennessee, and Seattle's passing game is called by offensive coordinator Darrell Bevell and run by Jackson. Those two previously were together with Rice in Minnesota.
Throw in an increased focus on the running game in the past month, and it's all added up to fewer opportunities for Williams, who has had 30 passes thrown his way in the nine games he's been active this season.
"I think we spread it more," Carroll said. "Mike's had some opportunities in the last couple weeks that he didn't capitalize on. We're still going to him. We've given him a lot of balls. It's just unfortunate that the numbers aren't working out."
