Fresh off losing the middleweight belt to Georges St-Pierre at UFC 217, Michael Bisping (30-8-0) has stepped in on short notice to replace Anderson Silva and face Kelvin Gastelum (15-3-1) in the main event of Shanghai’s UFC Fight Night 122.

Silva was pulled from the card when USADA notified him of an potential anti-doping violation on Nov. 10.

Bisping stepped in only 24 hours later.

Gastelum is looking to return to the win column after being stopped by former champion Chris Weidman at UFC on FOX 25 in July.

UFC Shanghai is scheduled for Nov. 25 at the Mercedes Benz Arena. The current card includes:

Michael Bisping (30-8-0) vs. Kelvin Gastelum (15-3-1)
