But the 37-year-old Manning isn't focused on 2019 just yet.
"We'll kinda worry about next year next year," Manning told WFAN on Monday afternoon, according to the Bergen Record's Art Stapleton.
Despite the Giants' struggles, Manning is on pace to throw for 4,000 yards with two games remaining. Though the Giants were mathematically eliminated from postseason contention on Sunday, Shurmur said Manning will start Sunday's game against the Indianapolis Colts over journeyman Alex Tanney and rookie Kyle Lauletta, though he didn't say whether or not the other two quarterbacks would get a look.
"I think we're going to go with the players who give us the best chance to win," Shurmur said. "Wer're getting a lot of guys here in the game. We'll see if that's Kyle."
Manning has one year and $23.2 million remaining on his contract, and the Giants could save $17 million in cap space if they cut the long-time Giants quarterback. Given that, Shurmur said on Monday he hopes Manning returns next season.
"I think what's important is things you decide in the offseason is things you decide," he said. "Right now we got two games left and put a plan together to be in Indianapolis. We stay in the moment in that. After every game, practice we evaluate a players' performance in all positions. In offseason we know there's decisions."
