Bills rookie QB Manuel moves up depth chart after Tarvaris Jackson is released by Buffalo

The Buffalo Bills have released quarterback Tarvaris Jackson in a move that nudges rookie first-round draft pick EJ Manuel one step closer to winning the starting job.

The move was announced Monday, a day before Buffalo opens a three-day mandatory minicamp. The timing of the decision frees up additional practice time for Manuel.

That leaves Manuel competing with Kevin Kolb, a sixth-year player the Bills signed in free agency in April.

Jackson never received a shot in Buffalo after being acquired by the Bills in a trade with Seattle in August. The seventh-year player spent all of last season as Buffalo's third-string quarterback. Jackson then signed a one-year contract to return to Buffalo in February, believing he would have an opportunity to compete for a starting job.
