The Buffalo Bills may be considering cutting veteran quarterback Matt Cassel before the start of the 2015 NFL season. According to the league’s official website, as per ESPN writer Mike Rodak, Cassel has lost his status as the team's No. 1 quarterback to E.J. Manuel.

Rodak wrote that 33-year-old Cassel was the favorite before organized team activities were held, but now he is in danger of losing not only his starting job but his spot on the Bills' roster. Cassel has been in the league since 2005, largely as a backup QB for various teams. He played for the New England Patriots from 2005 to 2008, Kansas City Chiefs from 2009 to 2012 and Minnesota Vikings from 2013 to 2014.

The Bills traded for Cassel in March. He is set to earn $4.15 million if he makes the team. The Bills went 9-7 last season but missed the playoffs.
