Eli Manning isn't sure whether or not he'll play next season, but if he does play he doesn't want to be a backup.

Manning, who turns 39 on Friday, has never played for a team other than the New York Giants.

He isn't interested in serving as the backup to Daniel Jones in 2020.

"I doubt it. I doubt it," Manning said. "Backing up is not real fun."

Retirement is a much more realistic possibility for Manning after 236 career games and two Super Bowl MVPs.

"Yeah, everything is an option," he said. "That is the first decision, whether I want to continue to play or not."
