The Pittsburgh Steelers and the St Louis Rams will face off on Sunday in Week 3 of the NFL 2015 regular season, and this is a game that could have big implications on how the season goes for these two teams. Both could push on to a winning record with victory today, but for the loser, falling to 1-2 would already create an uphill battle in the race for the Playoffs. Today's game takes place from the Edward Jones Dome in St Louis, 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.

In many pundits' eyes the Steelers are favorites to claim the win today and move to 2-1. Pittsburgh will have Le'Veon Bell back and he could provide the boost needed to get the Steelers over the line for a second win of the season so far.

Bell is finally back following his two game suspension, and the Steelers have not done too badly in his absence, entering Week 3 with a respectable 1-1 record.

DeAngelo Williams has filled in for Bell during his absence, and he has done a fantastic job, carrying 41 times for 204 yards and three touchdowns through the opening two games.

However, make no mistake about it, having Bell back in business raises the Steelers to a whole new level, as last season he was in a different class. Last year, Bell carried 290 times for 1,361 yards and eight touchdowns.

Today could end up being a long day for the Rams' run defense if they don't get to grips with Bell early on.

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.
