The regrettable Kevin Kolb era in Arizona is ending soon.

NFL.com's Ian Rapoport reported the Cardinals expect to cut Kolb soon, according to two sources briefed on the situation.

"He won't be on the roster by this weekend," one source told Rapoport.

The timing of the news makes sense. Kolb is due a $2 million roster bonus on March 17 and he's due $9 million in base salary in 2013. The Cardinals made it clear that Kolb would have to take a significant pay cut to remain with the team. It sounds like that's not going to happen.

It's quite possible that the Cardinals simply decided that Kolb was not a fit for Bruce Arians' vertical offense. With Drew Stanton now in place after signing in free agency, the Cardinals now look comfortable enough at the quarterback position. They have Stanton, Brian Hoyer, Ryan Lindley and John Skelton on the roster. We'd expect Lindley or Skelton to be released and the Cardinals will probably add a quarterback in the draft.
