His co-main event fight with Dan Hardy at UFC Fight Night 24 has only just been officially announced, but there’s already concern that Anthony Johnson may not be fit in time to fight on March 26th.

“Hope my knee heal up. Twisted it pretty good,” Johnson revealed on Facebook today.

That’s not a good sign considering that ‘Rumble’ has been plagued with a recurring knee injury for several years, and has in fact just spent well over a year out due to the problem.

It’s an unfortunate situation for the fighter who is pound-for-pound one of the most devastating strikers in the UFC, with all five of his Octagon victories coming inside the distance, three by KO, two by TKO.

Persistent knee troubles like this at the age of just 26 is a real concern, and to add to his woes he’s had trouble keeping his weight down during his lengthy injury absences which has already caused him to come in as much as 6.5lbs overweight for fights twice in the UFC.

That could play a factor in his ability to fight in March as if he does have to nurse a knee injury during this training camp it will restrict his ability to get into fighting shape and cut down to the 170lb limit effectively.

There’s still two months until the fight though so fingers crossed that this doesn’t prove to be another serious injury and the bout with Hardy, which has ‘Fight Of The Night’ written all over it, can go ahead as planned.
