Receiver Percy Harvin, who has missed the past three games with a sprained left ankle, will not practice today and could miss a fourth straight game or more.

Asked today if there's a fear that Harvin's season is over, coach Leslie Frazier said, "It's hard to say. It's hard to say."

Frazier was evasive when talking about Harvin's injury today.

"We probably won't have Percy out here today," he said. "I can't go into a whole lot of detail about his injury. I know there are a lot of reports out there about the extent of it. But he's done pretty much the things that the trainers have asked him to do. But he won't be practicing today."

Asked if there "are any other issues" with Harvin besides his ankle, Frazier hesitated.

"It's a ... I know that he wants to win like we do and I'm sure he's going to do everything he can to do what he has to do to help our football team," Frazier said. "And we'll see where it goes."

Frazier also said he'd have a better idea on Thursday as to whether Harvin will be able to play on Sunday against the Bears.

Frazier also said defensive end Jared Allen (back spasms) "probably will be limited" in practice today. He expects Allen to play on Sunday though. The rest of the players should be available to practice, Frazier said.
