Michael Bisping is getting right back on the horse.

A week after losing the middleweight title to Georges St-Pierre at UFC 217, Bisping has agreed to fight Kelvin Gastelum in the main event of UFC Shanghai in two weeks, MMA Fighting has learned.

Bisping replaces Anderson Silva, who was provisionally suspended by the United States Anti-Doping Agency on Friday and subsequently removed from the card. Silva failed an out-of-competition drug test administered by USADA on Oct. 26, however, it’s unknown at this time which substance he tested positive for.

Bisping (30-8) saw his five-fight winning streak snapped last week at Madison Square Garden when he was submitted by GSP. This fight would mark his second in China. He defeated Cung Le in Macau a little over three years ago.

Meanwhile, Gastelum (13-3, 1 NC) is looking to get back on track after getting submitted by Chris Weidman in July.

The UFC is expected to announce the new headliner imminently.

The event, which takes place at the Mercedez-Benz Arena in Shanghai on Nov. 25, will mark the promotion’s first card on mainland China, and it will air exclusively on UFC Fight Pass.
