Divas Champion Melina injured
The new year has started off on a sour note for Divas Champion Melina.
After suffering an injury in a match on Dec. 29 in Manchester, N.H., Melina underwent an MRI today, which confirmed that she tore her left anterior cruciate ligament (ACL). Due to this, she will be out of action for six months and have to forfeit her Divas Championship.
This unfortunate setback brings an end to Melina’s successful reign as champion, a title she has held since she debuted on Raw on Oct. 10 as a part of the Tri-Brand Diva Trade.
With the Divas Championship now vacant, an Eight-Diva Tournament to crown a new champion will begin on Raw tonight. Maryse defeated Brie Bella in the first match of the tournament.
