Minnesota Vikings quarterback Brett Favre told ESPN he remains uncertain about whether his record streak of consecutive starts will be extended to 298 regular-season games against the New York Giants.
The veteran quarterback will have one more day to heal thanks to a snowstorm that hit Minnesota on Saturday. With the Minneapolis airport closed, the Giants are stranded in Kansas City and the game, which was supposed to be played at 1 p.m. ET Sunday, has been postponed to Monday.
Favre has accepted the possibility his sprained right shoulder might not be healthy enough for him to play.
"I'm probably as confused as I've ever been about whether I should play,'' Favre told ESPN's Ed Werder. "I really don't know. Of all the games I've played during the streak where I've been injured, this is probably the most indecisive I've been.''
While he has participated on a limited basis in the Vikings' practices the past two days, Favre acknowedged he has been limited to the kind of light tossing captured by the media during the brief open access period Friday.
He did not throw in Saturday's walk-through.
Vikings coach Leslie Frazier said Favre will have to demonstrate in a pregame throwing session that he's capable of making all of the necessary throws in the game plan for the coaching staff to allow him to play.
"We would have to see him make some of the throws he'd have to make in the game, and he understands that," Frazier said.
Frazier also said the only way Favre will play is if he can protect himself, make all the throws and play the entire game. Giving him a snap or two at the beginning of the game to keep the streak going is not an option. The team is still considering giving Favre a painkilling injection to help him through it.
Receiver Percy Harvin is listed as doubtful with migraines that have kept him away from the team facility for more than a week, including last weekend's game against Buffalo.
Left guard Steve Hutchinson (broken right thumb), defensive end Ray Edwards (sprained right ankle) and third-string quarterback Joe Webb (hamstring) all are listed as questionable. Cornerback Chris Cook (knees) and safety Tyrell Johnson (knee) are out.
Favre was injured on the third play against Buffalo last Sunday when Bills linebacker Arthur Moats blindsided him and drove him into the turf. He watched the rest of the game from sideline and did not practice Wednesday or Thursday.
"The type of guy he is, the only [way he's not] on the field is if the sky's falling," Vikings tight end Visanthe Shiancoe said.
The Giants (8-4), stuck in Kansas City on Saturday night, have one of the best defenses in football and are tied with the Packers for the league lead in sacks.
If Favre cannot play, Tarvaris Jackson will start. He completed 15 of 22 passes for 187 yards with two touchdowns and three interceptions in the 38-14 victory over the Bills last weekend. Jackson said he got almost all of the reps in practice this week and is ready to go if Favre can't make it.
"I'm ready to play," Jackson said. "Regardless of what happens, I'm ready to play football."
Jackson was a second-round draft pick in 2006 and former coach Brad Childress tried to groom him as the quarterback of the future. But inconsistent play led the Vikings to bring in Favre last year and coax him back in August for one more season.
"I mean this whole situation has been a difficult situation," said Jackson, in the final year of his contract. "I'm not going to even sit here and act like it hasn't. It's been a difficult situation, but I just try to make the best out of it.
"It's a privilege to be in this league and I'm not promised anything. So I just try to come out here and be the best player I can be and the best teammate I can be."
Favre has played through countless injuries over the last 18 years, never moreso than this season when he has struggled with two broken bones in his left foot, 10 stitches in his chin from a hit against the Patriots, tendinitis in his throwing elbow and calf, back and neck soreness.
