The Denver Broncos will play the Arizona Cardinals on Thursday night as Week 4 of the NFL 2015 preseason sees all 32 teams in action. Although tonight's game is unlikely to feature Peyton Manning and most of the starters for more than a play or two, the action should still be competitive as backups and rookies fight it out for a spot in the 53 man active roster which is decided this Saturday. Tonight'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.

This will be the fifth season in a row that these two teams have played one another in the final preseason game, and although today's game will have no bearing on the regular season, the action should still be intensive as players look to book their places in the rosters with just days left until names are decided.

The Broncos have had a very strong preseason, and in particular their defense has been tight and shown great strength and depth. The defense has racked up 15 sacks through their first three games, and that should give them great confidence to do some damage when the regular season gets underway.

Week 3 was probably a more accurate assessment of where each team lies in their preparations for the new season, as most teams played a majority of their starters for half a game or more last week.

In Week 3, the New England Patriots managed to claim a 17-16 win over the Carolina Panthers, and they also received some good news this week with a court overruling the four game ban on quarterback Tom Brady.

In other games on Friday 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.

On Saturday last week, the Buffalo Bills stormed to a massive 43-19 win over the Pittsburgh Steelers, and the New York Jets were able to claim a 28-18 win over city rivals, the New York Giants.

In a low scoring game the Miami Dolphins claimed a 13-9 win over the Atlanta Falcons, and the Minnesota Vikings gained a win over the Dallas Cowboys by a score of 28-14.

The Cleveland Browns looked good in their Week 3 outing, defeating the Tampa Bay Buccaneers 31-7, where as the Washington Redskins also piled on the points in a 31-13 win over the Baltimore Ravens.

The Chicago Bears were unable to hold their own against the Cincinnati Bengals, losing 21-10, where as the Philadelphia Eagles and Green Bay Packers played out the highest scoring game of Week 3, with the Eagles coming out on top 39-26.

The Indianapolis Colts defeated the St Louis Rams 24-10, where as the Seattle Seahawks claimed a tight win 16-15 victory over the San Diego Chargers, and the Denver Broncos gained a 19-12 win over the San Francisco 49ers.

On Sunday in Week 3, there were two more games, and the Houston Texans won 27-13 over the New Orleans Saints, and the Arizona Cardinals defeated the Oakland Raiders 30-23.
