WSOF 13’s main event has gone from a title fight to a superfight – five rounds, but no title on the line.

Marlon Moraes (13-4-1) was set to defend his bantamweight belt against Josh Hill (10-0) in the WSOF 13 headliner. But an injury has forced Hill out, and he has been replaced by Cody Bollinger (16-2).

Just 10 days before the event, the bout will be contested at a 140-pound catchweight, WSOF President Ray Sefo told MMAjunkie. And as such, it will not be a title fight.

WSOF 13 takes place Sept. 13 at Sands Resort Casino in Bethlehem, Pa. The main card airs on NBC Sports Network following prelims on MMAjunkie.

Bollinger has won three straight fights since a loss in his Bellator debut nearly two years ago. He made his WSOF debut earlier this year and won a unanimous decision against Tyson Nam at WSOF 8. Then in July, he choked out Pablo Alfonso in the first round at WSOF 11. The 23-year-old Californian has 10 finishes in his 19-fight career.

Moraes won the WSOF 135-pound title in March with a dominant unanimous decision win over Josh Rettinghouse at WSOF 9. That victory kept him unbeaten for the promotion and gave him seven straight wins. Moraes burst onto the scene at WSOF 1 nearly two years ago when he upset former WEC champion Miguel Torres by split decision. He then knocked out Tyson Nam with a head kick at WSOF 2. Wins over Brandon Hempleman and Carson Beebe earned him the inaugural title fight against Rettinghouse, and he didn’t disappoint.

Canada’s Hill was looking to stay unbeaten. He returned to action in June after nearly two years on the sidelines and scored a first-round knockout of Mike Adams at WSOF Canada’s second event. That was enough to get him a shot at the red-hot Moraes, a title shot that will be put on hold.
