"I'm a competitor, and I don't want to go out like that," Marshall told ESPN this weekend. "I'm definitely not going out like that."
Marshall was injured in last Sunday's loss to the Los Angeles Chargers when he came down awkwardly out of bounds while trying to make a catch. He was taken to the locker room on a cart with his left cleat off.
He will be 34 years old next season and has a potential TV career in front of him, but Marshall says he is not thinking along those lines. He wants to play a 13th NFL season and is focusing on getting healthy.
"That's my mindset right now," he said.
Marshall signed a two-year contract with the Giants in the offseason. He was one of three Giants wide receivers -- along with Odell Beckham Jr. and Dwayne Harris -- to suffer season-ending injuries last week.
He had 18 catches for 154 yards with zero touchdowns this season before the injury. He needs 41 receptions to become the 15th player in NFL history to record at least 1,000 career receptions.
