A middleweight bout between Anthony Johnson and John Howard has been removed from the ‘UFC On Versus 1’ card on March 21st after Johnson suffered a knee injury.

It’s not the first time ‘Rumble’ has had trouble with his knee – he pulled out of the TUF 9 finale last year for the same reason. It’s unclear at this stage whether his latest injury is related or not.

The two fighters had become embroiled in a war of words that has started almost a year ago when Johnson accused Howard of backing out of a fight with him.  With Johnson now injured it might be quite some time before the two finally get a chance to settle their differences in the octagon.

Meanwhile Howard is now set to face a UFC newcomer Daniel Roberts, according to the Boston Herald.

Roberts is currently 9-0 as a professional MMA fighter.  He last fought in January, defeating Anthony Macais (25-12) by submission due to strikes in the first round.

Speaking about the rearranged bout Howard told the paper, “If you’re a UFC fighter, you’re a top fighter. You can’t take nobody lightly. I’m not taking this guy lightly. I’m not like, ‘Oh this is just some stupid guy coming to the UFC.’ I’m not thinking that. I’m training just as hard. Anybody that fights for the UFC, I don’t take them lightly at all.”

Howard was also level-headed about his long-awaited fight with Johnson being postponed.

I feel that if you got an injury, you got an injury. I’ll let him be 100 percent. I don’t want to fight an 80 percent or 90 percent Anthony Johnson. I want to fight a 100 percent Anthony Johnson. The beef is for real, but I don’t kick a dog while he’s down. That’s not my style.”
