A mixed martial arts fighter once featured in Spike TV's "The Ultimate Fighter" series has pleaded an equivalent of no contest in Las Vegas to attempted sexual assault in an April 2010 attack on a woman at his home.

The Las Vegas Sun reports (http://bit.ly/n86j8I ) that 30-year-old Michael Whitehead acknowledged Monday he could face two to 20 years in prison at sentencing Jan. 19 and will have to register as a sex offender.

Whitehead had faced sexual assault, attempted sexual assault and lewdness charges after a 32-year-old woman accused him of attacking her while she slept at his home following a party.

Police say a second woman alleged Whitehead groped her.

Whitehead competes as "Iron Mike" Whitehead. He has a record of 26 wins and seven losses.
