Matt Hasselbeck is open to returning for an 18th NFL season at the age of 40.

"I haven't really made up my mind completely on it," Hasselbeck said. "You have to kind of count the cost to what it would mean. What you're saying 'yes' to and what you're saying 'no' to. My kids are getting older, but all in all I would say that I'm strongly leaning toward playing again. We'll see."

Hasselbeck has been a strong mentor for Andrew Luck with the Indianapolis Colts, but they could decide to sign a younger backup.

Hasselbeck was 5-3 as a starter in 2015.
