UFC light heavyweight Johnny Walker wants a crack at former middleweight champion Chris Weidman.
The Brazilian said he wants to try to avenge Anderson Silva's two losses to Weidman in 2013.
Walker called Weidman out on social media last week, expressing interest in a bout in February or March.
Weidman responded but did not immediately commit one way or the other.
Weidman is coming off a knockout loss in his 205-pound debut. He said last week that he has no plans to retire and that he wants to get back into the cage early next year.
The American knocked out Silva, one of the greatest fighters of all time, in July 2013 to win UFC middleweight gold. He followed that up with a second win over "The Spider" via an injury TKO that resulted in one of the worst broken legs in MMA history. Weidman dropped the title in December 2015.
Walker signed with the promotion just last year and made waves early, scoring knockouts of Khalil Rountree, Justin Ledet, and Misha Cirkunov. However, Walker suffered a quick loss in his last bout against Corey Anderson at UFC 244 on Nov. 2.
