As the NFL's 2013 regular season ends on Sunday, 20 non-playoff teams play their final game. At the same time, a number of head coaches will be on the sideline for the last time with their respective teams.

On my count, as many as 10 coaches are sitting on the hot seat and they could lose their job by Monday morning.

Gary Kubiak is already gone, getting axed in Week 14 because his Texans entered this season as a Super Bowl contender, but stumbled to a 2-11 record when he was replaced. Defensive coordinator Wade Phillips took over for him, but the Texans are still looking for their first win since Week 2. The Texans reportedly are ready to interview some candidates, including Penn State coach Bill O'Brien, so Phillips' job is not safe.
