Paddy Pimblett will face Rodrigo Vargas in one of the most anticipated fights on the UFC's return to London.
The Liverpool native was expected to take on Jared Gordon when the promotion lands at the O2 Arena on March 19, but now will face 36-year-old Vargas.
Tom Aspinall will headline the big fight night against Alexander Volkov, while Pimblett will likely participate in the co-main event given his massive star power since debuting last year.
