Nick Ring out vs. Constantinos Philippou at UFC 154 Tonight

Constantinos Philippou on Twitter:

"

. bad news guys! My fight got cancelled...Nick got sick and he can't fight.

Obviously, this is a bit of a setback for the UFC 154 card, which is set to take place tonight on pay-per-view.

This is a huge inconvenience for either fighter, as Philippou is looking to rack up his fifth straight win, which would throw him into the thick of the title picture for the middleweight division.

Ring, meanwhile, was trying to follow up on his controversial win over Court McGee and make good on his former prospect status.

No word yet on what Ring is sick with, however, he looked sluggish and exhausted at the weigh-ins yesterday (you can check out the video here). This adds another major fight that has been canceled in the UFC, which has had absurd struggles with injuries of late.

The fight was supposed to take place on the night's main card, meaning the UFC needs to bring another fight up from the preliminary card. Rafael dos Anjos vs. Mark Bocek has been elevated from the preliminary card to the main card in its stead (via Sherdog).

Dos Anjos is a strong submission fighter sitting on back-to-back wins and owning a 6-4 UFC record overall. Bocek, meanwhile, is a Team TriStar product who will be fighting in his home country.
