The San Francisco 49ers have had one of the best rushing attacks all season long. That is due to their three-headed monster at running back.

San Francisco has Tevin Coleman, Matt Breida, and Raheem Mostert. All three have had big moments this year and have been instrumental in the success of the 49ers.

Now they will be testing their undefeated season (7-0) against an NFC West division rival. The Arizona Cardinals to be exact.

Breida has been listed as questionable this week, but it appears he will be playing on Thursday night.

This is big news for the 49ers. Obviously, they have three great running backs. Due to that, one injury would not be the death of them in a game. However, it helps them to have as many running backs as possible.

A big part of the 49ers' game this year has been keeping all three as fresh as possible. San Francisco gives all three a fair amount of carries each week without running one too much. That keeps them all rested while tiring out the defense.

It also helps that Breida has been especially fantastic this year. The running back has 446 yards and one touchdown on 84 carries (5.3 yards per carry). He also has 12 receptions for 89 yards and another touchdown.

Those are numbers any team would definitely love to have. They are also numbers you would not want to have missing in an important divisional matchup.

As San Francisco looks to improve to 8-0 on the year, they received some good news ahead of their Thursday Night Football matchup. Breida has been one of their most important players on offense, and now they have him available against Arizona.
