The NFL world is still processing the fact that 44-year-old Philip Rivers is back on the Indianapolis Colts ... and that includes Cam Newton, who admitted he felt like it was a "slap to my face" he didn't get a call.
Newton spoke about the signing on his "4th&1" podcast ... where he clearly seemed annoyed that the Colts didn't check in on his availability.
When his co-host asked if Cam's work in the media gives off the vibe he'd be interested, Newton didn't agree with the narrative.
