According to his official MySpace page, UFC welterweight Anthony "Rumble" Johnson will be forced to pull out of his upcoming clash with Matt Brown due to a knee injury he suffered while training. Earlier today, Johnson updated his page with the following message, "NOT DOING WELL IM SORRY TO EVERY1 MY KNEE GOT JACKED UP TRAINING FOR MY FIGHT. NOT THE BEST OF TIMES BUT ILL MAKE IT AND COME BACK STRONGER. I ALWAYS DO!!!"

At this time, the extent of  the injury is unknown, but hopefully it's not serious and the talented welterweight will be back in the cage as soon as possible. Johnson was set to face Matt Brown during the TUF 9 Finale on June 20 at The Pearl at the Palms Casino Resort.
