Before the team's bye, Shurmur had said "we'll see" when asked if Manning would keep his starting job. The Giants are 1-7 and average 18.8 points per game, which is 27th in the NFL. Manning has been sacked a league-high 31 times.
Shurmur also said Tuesday that he will not suspend backup quarterback Lauletta for his arrest last week.
