Controversial Philadelphia Eagles back-up quarterback Michael Vick is preparing for what could be his first start since he was jailed in 2007 for his role in a dog-fighting ring.
First-choice quarterback Kevin Kolb suffered concussion in the Eagles' 27-20 defeat by the Green Bay Packers last weekend and under the NFL's rules he must pass a test before he can take part in practice prior to this weekend's trip to the Detroit Lions.
Linebacker Stewart Bradley is also currently sidelined with concussion and Eagles coach Andy Reid said he and Kolb had failed tests.
Reid says right now Kolb is not practicing, Vick is practicing and he's getting himself ready to play in that game.
Former Atlanta Falcons starting quarterback Vick was given an 18-month jail sentence for involvement in an illegal dog-fighting ring and after serving jail time was allowed back into the league with the Eagles.
The 30-year-old was used as an occasional back-up to Donovan McNabb last year but has risen in the pecking order since McNabb's move to the Washington Redskins.
Vick started in pre-season earlier this month but if he begins against the Lions it would mark his first regular season start since New Year's Eve, 2006, when he played for Atlanta against the Eagles.
