Philip Rivers has announced his retirement from the NFL after 17 seasons.

"It's just time," Rivers told the Union-Tribune. "It's just right."

Rivers played in 244 games, starting 240 of those contests.

The 39-year-old finishes his career ranked fifth all-time with 63,440 passing yards and 421 touchdown passes.

"I can sit here and say, 'I can still throw it. I love to play,'" Rivers said. "But that's always going to be there. I'm excited to go coach high school football."
