The UFC continues to be besieged by injuries as we can now add Heath Herring to the ever growing list of fighters unable to make it to fight night.

According to MMA Fanhouse Herring will not be able to face off against Cain Velasquez next month at UFC 99 in Germany due to an illness he has been suffering from for weeks which has left him unable to train.

The UFC has announced on their website today that Cheick Kongo will replace Herring and take on Velasquez at UFC 99. Kongo who is riding a three fight winning streak was last seen at UFC 97 in April where he defeated Antoni Hardonk by second round TKO. There has been some speculation that Kongo would receive a title shot sometime in the near future and a win over Velasquez will only add fuel to those flames.

Herring who hasn’t fought since being dismantled by current UFC champion Brock Lesnar at UFC 87 last August was to be Velasquez’s toughest opponent to date.

The young up and coming All-American wrestler from Arizona State is seen as the future of the UFC heavyweight division and a bout with Herring was surely going to show everyone what he is really made of. In his last bout against Denis Stojnic at UFC Fight Night in February Velasquez imposed his will and earned knockout of the night honors with a second round TKO.
