The rematch between Dustin Poirier and Eddie Alvarez will have to wait.

The good news is that, according to MMA Fighting, the UFC is looking to book a rematch between lightweight standouts Dustin Poirier and Eddie Alvarez, after their pulsating bout at UFC 211 ended in a controversial no contest.

The bad news? MMA fans will have to wait until around November, as 'The Diamond’ picked up a concussion and needs time to heal. Poirier's manager, Robert Roveta, told MMAF that they are taking his concussion symptoms 'very seriously'.

Poirier vs. Alvarez was one of the most exciting fights of the night, with both men electrifying the American Airlines Center with a wild exchange in the second round. Shortly after both fighters had been rocked, Alvarez landed a series of illegal knees to Poirier's head, and the 28-year-old was deemed unable to continue. Referee Herb Dean ruled the bout a no contest after declaring that 'The Underground King' was not looking to intentionally land any illegal strikes.

Poirier, however, will be filing an appeal to the Texas Department of Licensing and Regulation in the hopes of having the result overturned to a disqualification loss for Alvarez. The top-10 lightweight contender is medically suspended until June 28, but will be out of action much longer due to his concussion.

Poirier and Alvarez recently exchanged barbs on Twitter, and both men are excited about the rematch.
