Gray Maynard Injured, Jim Miller vs. Joe Lauzon Set for UFC 155

Injuries, injuries and more injuries.

Shortly after announcing that UFC heavyweight Shane Carwin had blown out his knee, the promotion has now revealed that lightweight Gray Maynard is sidelined from his UFC 155 bout with Joe Lauzon.

However, this fight has a ready replacement.

Jim Miller will be stepping in for Maynard against Lauzon, although it's uncertain if this bout will remain a title eliminator situation.

Maynard last competed this past June as one-half of the main event at UFC on FX 4, winning a split decision against Clay Guida. Notably, the match was critically panned by fans and pundits alike, as Guida opted to use frantic footwork in order to avoid Maynard's heavy hands.

Prior to that, Maynard came up short in two bids to take Frankie Edgar's lightweight title, with a split draw decision at UFC 125 and a fourth-round KO loss at UFC 136.

Miller has also fallen on hard times lately, losing in violent fashion against Nate Diaz by guillotine submission at UFC on Fox 3. Miller's sitting at 1-2 in his last three matches, with his other loss coming at the hands of current UFC lightweight champion Ben Henderson.

UFC 155 will be the promotion's last event in 2012, taking place in Las Vegas at the MGM Grand Garden Arena on December 29th.

It's unknown what spot Miller vs. Lauzon will take on the card, which is planned to feature a heavyweight title fight between Junior dos Santos and Cain Velasquez as the main event. Alistair Overeem was originally planned for the bout, but is serving suspension for elevated testosterone levels following a positive drug test.
