Andy Reid will hold a press conference in about a half hour to explain, but as of now it appears that Michael Vick will be the Eagles starting quarterback for the remainder of the season.
Given that the Eagles are putting on a full press conference in front of the cameras, it's a fair assumption that Vick isn't simply starting another week due to an injury to Kevin Kolb. You may remember that Reid said Kolb would return as the team's starting quarterback after the Eagles 35-32 win in Detroit. It appears that he has had a change of heart in the last 48 hours.
We'll update as news comes out.
