Frank Reich believes Philip Rivers will play multiple seasons with the Indianapolis Colts.

"The spirit of [negotiations] was, we're in this together and as long as Philip wants to play, wants to be here," Reich said Monday. "It's the NFL, we know he has to prove it. We have to prove it as a team to keep him wanting to play. I can just tell you from the previous relationship [with the Chargers], I really believe it's Philip's intent to play multiple years. I personally believe he's more than capable of multiple years."

The Colts signed Rivers to a one-year, $25 million deal.

Reich was a member of the Chargers' coaching staff from 2013 to 2015.
