TEMPE, Ariz. -- Arizona Cardinals wide receiver Larry Fitzgerald, who didn't practice for the third straight day because of a Grade 2 MCL sprain in his left knee, will be a game-time decision Sunday against the Seattle Seahawks.

Coach Bruce Arians made the announcement Friday. The 31-year-old Fitzgerald, who was officially listed as questionable, injured his knee last Sunday against Detroit.

"Practice at his age right now is overrated sometimes," Arians said. "Sometimes it can be good for you. But we'll see if he can capably play on Sunday at the game."

Arians said the deciding factor will be Fitzgerald's ability to "play at a certain level and not hurting us and being able to help us." Arizona's 9-1 record leads the NFC West by three games over Seattle and San Francisco.

If Fitzgerald cannot play, Arians said the combination of Jaron Brown, John Brown and Ted Ginn will fill Fitzgerald's role. John Brown is Arizona's second-leading receiver and leads the team with five touchdowns. Ginn has seven catches for 111 yards, and Jaron Brown has caught six passes for 76 yards.

"The other guys have had a real good week of practice, and they're more than capable of picking up for him," he said.

Fitzgerald last missed a game in Week 13 of 2007. Since then, he has played in 110 straight games, currently the second-longest streak for active receivers. Fitzgerald is Arizona's leading receiver with 46 catches for 658 yards.

"Knowing the warrior that he is, he's played a lot of times he probably shouldn't have just because he's going to do it for his teammates," Arians said. "And that mentality would be the same this Sunday, I'm sure."

Cardinals rookie defensive tackle Ed Stinson is officially out for Sunday's game with a toe injury. Arians said Stinson won't travel.

A day after being added to the team's injury report, Sam Acho (neck) is listed as probable. Linebacker Lorenzo Alexander (knee), RB Andre Ellington (hip/foot), LB Larry Foote (hip), FB Robert Hughes (hamstring), S Rashad Johnson (back) and NT Dan Williams (elbow) were all upgraded to full Friday and were listed as probable.
