(WSCR) At this point it’s no secret that Jay Cutler and Mike Martz aren’t getting along, but now there appears to be some obvious video evidence.

Cutler was caught on camera Sunday night shaking his head while taking in a playcall through his headset and then moments later a parabolic sideline mic picked up some unkind words that appear to be pointed at Martz.

The video shows Cutler breaking the huddle and screaming something towards the sideline. While the audio isn’t 100 percent clear, he appears to be saying: “Tell Martz I say f””k him.”
