Seattle Seahawks running back Shaun Alexander and quarterback Matt Hasselbeck returned to practice with mixed results Wednesday, and the team’s medical staff will determine Friday whether they will play Sunday against the 49ers.

Hasselbeck favored his sprained right knee for part of the practice, and Alexander ran 11 plays with Seattle’s first-team offense for the first time in seven weeks since breaking his left foot. The 2005 NFL rushing champion ran at less than full speed but showed no signs of pain in a foot that remains cracked, according to X-rays taken this week.

Doctors are focusing on how Alexander feels to determine when he can return. Wednesday, he sounded as if he was ready to play against the 49ers.

``It’s all about what my foot can take,’’ Alexander said. ``I think that’s going to be the greatest test (when I ask for) 50 carries—which is probably what I will ask for when we get to Friday and I still feel good.

``We’re still in a we’ll see, but today was good.’’

Hasselbeck was limping by the end of the 25 plays he ran with the scout team.

Hasselbeck was sharp early in practice. By the end, his deep passes were underthrown. His limp gradually became more prominent when he carried out fakes after handoffs. He also appeared to avoid planting on his right leg while throwing.

``I thought today went very well,’’ Hasselbeck said. ``I feel like I’m on schedule. And I’m extremely encouraged. The big question would be just getting tackled and getting bent up in the bottom of a pile like a pretzel. I don’t know how you plan for that.’‘
