The Denver Broncos and the Atlanta Falcons will clash on Sunday in a big game for Week 5 of the NFL 2016 regular season. The Broncos will be hosting today's game at Sports Authority Field with a scheduled start time of 4.05 p.m. ET, and will be favorites to claim the win in front of their home fans. The game can be watched on TV on the Fox network or online through live stream via the link below.

The Broncos will be looking to maintain their perfect start to the season today with a fifth win.

Last week they claimed an easy win on the road against the Tampa Bay Buccaneers, sweeping them aside 27-7 in a result that never looked in doubt.

That result moved them to 4-0 and although the Falcons will provide a very different and stern test today, the Broncos will already be one of the favorites to make the Super Bowl this year again.

The Broncos success has been built - as it was last season - on their immense defensive unit. They have the ability to get in the face of opposition quarterbacks and pressure them into making mistakes at pivotal points in the game, and that is exactly what happened last week against the Buccaneers, who were unable to score a solitary point across the final three quarters.

The Falcons will know they have a lot of work to do today to get any kind of result, although they will be in confident mood after last week's high scoring win over the Carolina Panthers.

That 48-33 victory moved the Falcons to 3-1 and if they can get a fourth win of the season today and take down one of the NFL's biggest and most favored teams for this year's Playoffs then it will put them in the perfect position to make a drive for this season.

Earlier this week on NFL Thursday Night Football the Arizona Cardinals gained a valuable road win over the San Francisco 49ers.

Both teams entered the clash on 1-3, and both knew that they were facing almost must-win situations to salvage their seasons.

Following a tense first half the teams were level on 7-7, but the second half saw the Cardinals turn the screw and they pulled away to win the encounter 33-21.

The result moved the Cardinals onto a much more respectable 2-3 although they still have a lot more work to do over the coming few weeks to get themselves back into postseason contention. The 49ers meanwhile suffered their fourth defeat of the season in just five weeks and that leaves their season more or less in tatters. It's hard to see how they can turn their season around from here, and already it may be more about re-building for next season than having any realistic chance of making a run for the Playoffs this year.

Arizona managed to claim 17 points from three turnovers by the 49ers in the game, including two interceptions by Blaine Gabbert as well as a a fumble kickoff return by Chris Davis.

49ers coach Chip Kelly said after the game: "I don't think anybody played well on offense. Nobody. I don't think we protected well enough, I don't think we threw it well enough and we had too many drops and two interceptions."

Meanwhile, defensive lineman Calais Campbell said, "We've been saying all week it just starts with one. Just get one win and try to stack them. We've been a team in the past that can rip off a bunch of them. ... Now we have to figure out what we can do to keep that ball rolling."
