With The Chase race one in, NASCAR driver rivalries are heating up once again!

NASCAR.com published a list of rivalries to keep our eye one.  NASCAR fans know that even if officials say keep it off the track, they rarely keep it off the track.

This past week, Truex Jr. called out Harvick saying he hit him on purpose.  Maybe this is something to watch next week!

So, what do you think – do rivalries heat up once The Chase is on?  Here are some duos we will be watching:

Matt Kenseth vs. Brad Keselowski

It all stated in 2014 with these 2 both on and off the track.  The past week, Kenseth was not happy with Keselowski's racing which caused him to cut a tire, crashing and finishing 38th.

Kyle Busch vs. Brad Keselowski

Both drivers admit there is no love lost between the two of them.  They call each other names both on and off the track.  Although they have been semi quiet lately, don’t count on this rivalry staying that way

Ryan Newman vs. Tony Stewart

This rivalry is fresh and poised to be the one to watch!  Last week, Newman believed Stewart intentionally hit him. He even called out Stewart, saying he should be retired after making a move like that. Newman is out of the chase now, will he take Stewart with him?  NASCAR will be watching this one!
