The NFL world was stunned when the Colts signed 44-year-old QB Philip Rivers to replace an injured Daniel Jones ... and that includes the team's top wide receiver, Michael Pittman, who told TMZ Sports he was "shocked!"
While that was his first emotion, Pittman told us there was also excitement about the move, especially since Rivers was his first quarterback after entering the league in 2020 (it was PR's last season, until now, of course).
