The 41-year-old quarterback missed his second straight day of practice Thursday with a sprained SC joint in his throwing shoulder, and interim head coach Leslie Frazier said it will likely be a game-time decision on whether Favre will start against the New York Giants.
On Wednesday, Frazier said he was optimistic about Favre playing and expected him to take the field and test it out in practice on Thursday. After Favre was unable to do that, Frazier was asked if he remained as optimistic.
"I'm hopeful that it will work," Frazier said. "Just hoping that things will be better tomorrow than they were today."
The plan is for Favre to try and do some work in practice Friday, the final full day of practice before the game Sunday. The team also has a light walkthrough Saturday, but Frazier said he would be OK with Favre not doing any work all week and then playing on Sunday if the quarterback felt up to it.
"If he could go out in pregame much like we did with Adrian [Peterson's ankle] last week, and he moved around and threw the ball well, yeah, we'd put him out there if it looked good enough for us to do it both medically and from a physical standpoint," Frazier said.
Favre was not available to reporters Thursday. He said Wednesday he hoped to make a decision about his availability as early as Friday, depending on how the week went. He was injured on the third play of the game last Sunday when Buffalo Bills linebacker Arthur Moats blindsided him on a pass play.
Favre watched the rest of the game from the sideline, with Tarvaris Jackson filling in during the 38-14 victory.
"We were hoping that he'd be able to do something today," Frazier said. "The fact that he couldn't just means we'll move it back another day. Friday's not the end of the world. If he can do some things tomorrow that will be great, and hopefully that will be the case."
Favre isn't the Vikings' only injury concern. Receiver Percy Harvin has not been at the team's headquarters this week, staying home to treat a migraine that has bothered him for more than a week now. Harvin did not play against Buffalo last weekend and Frazier said the team is having him meet with doctors to address a problem that has plagued him for most of his adult life.
Left guard Steve Hutchinson did not practice and is still trying to determine if he can play with a broken right thumb that caused him to miss last week's game. Defensive end Ray Edwards (high ankle sprain), cornerback Chris Cook (knee) and safety Tyrell Johnson (knee) also did not practice.
