Nick Diaz vs. Robbie Lawler 2 In The Works As UFC 266 Co-Main Event

The long wait for Nick Diaz to fight again is could be over.

After more than six years away from the sport, Diaz is currently targeted for a rematch against Robbie Lawler with the fight expected to serve as the co-main event at UFC 266 on Sept. 25 in Las Vegas, MMAFighting.com reports.

TSN Sports' Aaron Bronsteter reports a Nick Diaz vs. Robbie Lawler fight is in the works as a co-main for an event in September, citing UFC President Dana White first revealed the possible matchup to TSN on Wednesday.

MMAFighting.com's Ariel Helwani reports the fight is being discussed for UFC 266 and would serve as co-main for a potential main event featuring Alex Volkanovski vs. Brian Ortega for the 145 title.

Helwani reports that nothing has been signed at this time, but rather discussed and in the works —  all signs are pointing to the fight coming together as Diaz looks to restart his career after last competing in 2015.

The duo first met at UFC 47 in 2004, where Diaz won via second-round KO.

Diaz, known as one of the most polarizing fighters in the history of the sport, is a one-time welterweight title contender with an impressive resume of past opposition, MMAFighting.com reports. The 37-year-old veteran has wins over B.J. Penn, Paul Daley and Frank Shamrock.

Lawler, a former UFC welterweight champion, has struggled in his most recent fights with losses to Colby Covington and Neil Magny in his most recent appearances. MMAFighting.com reports that he'll attempt to correct course while facing off with an old foe.
