Arizona Cardinals quarterback Drew Stanton reportedly played the 2017 season with a torn ACL in his knee.

Per NFL Network's Ian Rapoport, Stanton had been playing with "a thread" of an ACL for years before it finally gave out.

Rapoport added Stanton is not planning to have surgery because he's learned how to manage the situation.

Cardinals wide receiver Larry Fitzgerald said after the team's Week 17 win over the Seattle Seahawks that Stanton played the final two weeks of the season with a torn ACL.

Stanton missed five games with a sprained right knee suffered in Week 10 against the Seahawks. He was replaced by Blaine Gabbert until he returned against the New York Giants in Week 16.
