ALBUQUERQUE, N.M. -- Holly Holm, the world's former No. 1-rated female boxer, has pulled out of her much-anticipated UFC debut.
Promoter Lenny Fresquez told the Albuquerque Journal on Thursday that Holm suffered a neck injury in training and had to withdraw from her scheduled fight with Colorado-native Raquel Pennington on Dec. 6 in Las Vegas.
Last year, Holm, 32, announced her retirement from boxing to focus on an MMA career and signed with UFC in July after months of negotiations. She has a 33-2-3 record as a boxer and is 7-0 as an MMA fighter.
