Vikings interim coach Leslie Frazier expects that quarterback Brett Favre will test out his sprained right shoulder in practice on Thursday after sitting out Wednesday. "I talked with him just a little bit earlier today and we were just talking about his health and just seeing where he was," Frazier said this afternoon during an interview with Chris Russo on Sirius XM's Mad Dog Radio. "He probably won't practice [Wednesday] but we'll get a chance to see how he looks on Thursday and just try to make a determination based on that, you know, how things will look for Sunday. But we're all hoping that he'll be healthy enough to play. He's still a great quarterback and if he's able to play it gives us a great chance to win against New York." Favre suffered a sprained sternoclavicular joint in his throwing shoulder on his first pass attempt in Sunday's victory over the Buffalo Bills. He did not return to the game and was replaced by Tarvaris Jackson. Favre not practicing on a Wednesday would not be a big deal. He has sat out four of six Wednesday practices since he suffered a stress fracture in his left ankle and another fracture in his left heel in late October. Russo mentioned to Frazier that he is in a tricky spot in part because of Favre's NFL-record starting streak (297 games) and also because the Vikings are mathematically alive in the playoff race. "Brett's our starting quarterback and if he's healthy, I mean, he's gonna be out there," Frazier said. "If there's any definition of an Iron Man, it would be Brett Favre. I mean, it's incredible what he's accomplished in his career. For a quarterback to play that many consecutive games? I don't think that's a streak that will ever be broken. But he can still play at a high level and there's no question in my mind, if he's healthy he'll lead us to a win on Sunday."
