Today's game takes place from the Nissan Stadium in Nashville, Tennessee, and has a scheduled start time of 1 p.m. ET. The game can be watched on TV on the CBS network or online through live stream via the link below.

The Colts did not expect to find themselves in such a perilous position already in the season, however, at 0-2 coming into Week 3 it is imperative that Indianapolis find a way to claim a win today to avoid falling to 0-3.

A Week 1 loss to the Buffalo Bills seems to have knocked the Colts confidence, as that opening game 14-27 loss was followed up on Monday Night Football with a 7-20 loss to the New York Jets.

The Jets successfully shut down the Colts offense for almost the entire game, only allowing 7 points in the final quarter.

The Colts must find a way to get themselves back in gear today, as only three teams over the past 25 years have comeback from an 0-3 start to the season to make the Playoffs.

Week 3 is already crunch time for a number of NFL teams. Earlier this week on NFL Thursday Night Football, the New York Giants faced a massive game against the Washington Redskins. The Giants were 0-2 after their opening two games, and they knew if they slipped to 0-3 their season was almost guaranteed to be over before it had even got going.

The 1-1 Washington Redskins were hoping to move to 2-1 to compete with the NFC East division leading Dallas Cowboys, and at the same time all but eliminate one of their main rivals from contention for the postseason.

But when the push came to shove the Giants showed that they are still alive and kicking. New York came out of the blocks fast, building a 12-0 lead after the first quarter, and it was a lead they would refuse to give up despite some strong pressure from the Redskins in the fourth.

The Giants had lost their opening two games after getting themselves into winning positions and some must have thought they were heading the same way on Thursday. However, they finally held on to a second half lead and clinched a 32-21 win, with the highlight being a 30 yard Odell Beckham Jr touchdown catch.

The Redskins must have seen how the Giants collapsed under pressure in the fourth quarter against the Dallas Cowboys and Atlanta Falcons in Weeks 1 and 2. But even though the Redskins pushed hard in the fourth, scoring 15 points in the final quarter, the Giants responded to the pressure and recorded 14 points themselves to keep themselves in front.
