Another head coach is reportedly on the chopping block

Management is losing patience.

The boisterous Buffalo Bills head coach, Rex Ryan, may not make it through the week, much less then end of the season if he doesn't turn things around in a hurry, per CBS:

"It would take an overwhelming performance down the stretch for Ryan to be back in 2017, the sources said, and he could be out as soon as Monday, depending on the team's results against Pittsburgh."

Coming off a loss to the Oakland Raiders, the Bills dropped to 6-6 on the season after an 8-8 finish last year.

According to the report, the up-and-down play of quarterback Tyrod Taylor, the limited passing offense and the hiring of Rex Ryan's brother, Rob, as the defensive coordinator are sore spots within the organization.

The report also notes management's intrigue in rookie quarterback Cardale Jones.

In six years as New York Jets head coach, Ryan put together a 46-50 record. Ryan is just 14-14 in two years at Buffalo.
