The San Francisco 49ers will play the Denver Broncos in a massive clash in Week 3 of the NFL preseason. Both of these teams will believe they are serious contenders for this year's Super Bowl, but that means they will want to make a lightning fast start when the regular season gets underway in a few weeks. Week 3 is considered a dress rehearsal for the opening games, so expect both teams to feature a lot more starters, for a lot longer than we've seen in recent weeks. Today's game has a scheduled start time of 9 p.m. ET and takes place from Sports Authority Field at Mile High. The game can be watched online through live stream via the link below.

With starters from both rosters expected to get at least half a game tonight, this should be a mouthwatering clash for all NFL fans.

The Broncos come into today's game following a 14-10 victory over the Houston Texans last week. They did not have it all their own way though, and had to come from behind late on to claim the win.

Peyton Manning featured for the first time, going 8 of 14 for 52 yards. Expect him to get even more time on the field tonight.

Week 3 in the NFL preseason is a big one, with three games taking place on Friday night, and 11 more taking place on Saturday.

On Friday, the New England Patriots were able to obtain a road win over the Carolina Panthers 17-16, and although it was by no means anywhere near a complete performance, they will be pleased to have come out on the right side of the result.

The Patriots are of course dealing with the loss of Tom Brady, who through DeflateGate will miss the opening four games of the regular season. So their top priority is to make sure they cover his big absence well enough not to allow the opening games to undermine their season and push for another Super Bowl.

In other games on Saturday the Kansas City Chiefs continued to look impressive in their preseason warm-ups. The Chiefs claimed a very convincing 34-10 victory over the Tennessee Titans, and their preseason form will give them hope that they can make a significant impact in the new season.

Meanwhile, the Detroit Lions looked far from their best, but still saw off a Jacksonville Jaguars team that looks like it is on the way up, but still a few seasons away from being able to seriously compete for postseason spots. The Lions came away from Jacksonville with a 22-17 victory.

Saturday's games feature 11 match ups, and being Week 3 fans can expect a much more intensive affair, with starters being given more field time as final preparations for the new season are put in place. Week 3 is traditionally a time where teams look to ramp things up significantly from previous weeks, and can be more intensive than Week 4 as teams look to be more cautious about injuries in the final preseason week as the new season gets close.
