Former WWE star Brock Lesnar vs. Frank Mir is scheduled to take place at UFC 98 on May 23 in Las Vegas, NV to determine the undisputed UFC Heavyweight Champion.

This is a rematch after the two fought last February in what was Lesnar’s UFC debut where he lost to Mir in the first round via submission. Lesnar defeated Randy Couture at UFC 91 on November 15 to capture the UFC Heavyweight Title, while Frank Mir defeated Antonio Rodrigo Nogueira at UFC 92 on December 27 to capture the interim UFC Heavyweight Title.
