The only thing that changed for three-time Pro Bowl passer on Thursday from Wednesday was the color of the team cap he was wearing - conspicuous, neon green instead of blue. He again stood and watched practice with a black wrap over his bruised right knee.

One day after coach Mike Holmgren said Hasselbeck "has to play" for the Seahawks (1-3) against the Packers (2-3), third-string quarterback Charlie Frye again ran the offense. No. 2 quarterback Seneca Wallace is out indefinitely with a calf injury.

Offensive coordinator Gil Haskell reiterated Hasselbeck will play even if he doesn't practice Friday, but Haskell would prefer Hasselbeck got one day of work in this week with a jumbled receiving corps.

Haskell was asked if Seattle's starter since 2002, who set most of the team's passing records for a season in 2007 but is the NFC's lowest-rated passer this season, is one guy who doesn't need to practice to play.

"No, you're never there as a quarterback, because it's the rhythm," Haskell said. "Especially now, with the new receivers."

Seattle had six wide receivers hurt through last month.

Koren Robinson had a second consecutive good day of practice and says his sore knee feels better than at any time since he signed last month. He may make his season debut against the Packers, for whom he played in 2006-07. Robinson was smiling Thursday over the birth over his 5-day-old baby girl.

Bobby Engram will play in his second game of the season with Keary Colbert and Billy McMullen also in prominent roles. The latter two signed last month.

"Every team knows that they're going to face adversity at some point and ours came just right at the beginning," Hasselbeck told reporters in Green Bay this week.
