New Bellator signee Gegard Mousasi will make his debut for the promotion in October.

Bellator officials today announced that Mousasi (42-6-2 MMA, 0-0 BMMA) will face Alexander Shlemenko (56-9 MMA, 12-3 BMMA) in the main event of Bellator 185, which takes place Oct. 20 at Mohegan Sun Arena in Uncasville, Conn.

Additionally, top light heavyweights clash as Muhammed Lawal faces Liam McGeary.

Mousasi, the No. 6 ranked fighter in the USA TODAY Sports/MMAjunkie MMA middleweight rankings, signed a multi-fight agreement with the Viacom-owned promotion earlier this week. He brings with him a five-fight winning streak.

Meanwhile, Shlemenko is a former Bellator middleweight champion who brings a six-fight winning streak to the cage. A seventh win – a February 2015 stoppage of Melvin Manhoef – was overturned to a no contest when Shlemenko tested positive for “significantly elevated” testosterone-to-epitestosterone ratio.
