The Eli Manning era as the Giants' starting quarterback could be down to its final 60 minutes, Monday night against the San Francisco 49ers. 

Earlier this week, Giants head coach Pat Shurmur wouldn't commit to Manning starting beyond this week, after his team limped to the bye week at 1-7. 

After 15 seasons and two Super Bowl championships, Manning says he doesn't feel any differently about this week's game than any that came before. 

"We worry about this week," Manning said prior to Thursday's practice, when asked if he's worried that Shurmur might make the switch to rookie Kyle Lualetta in the coming weeks. "We have the 49ers. I have a job to do. I'm going to do it to the best of my availability." 

Manning enters Monday completing 68.3 percent of his passes for 2,377 yards with eight touchdowns and six interceptions.

Had Lauletta not been arrested for multiple charges stemming from a traffic violation, it is conceivable that the fourth-round rookie could have gotten the start in San Francisco. 

During Shurmur's conversations with Manning during the bye week, the first-year head coach challenged the 15-year veteran quarterback to take the decision out of his hands by playing better in the second half.
