Nick Diaz is set to make his return to UFC after six years away with a bout against Robbie Lawler, but his competitive schedule beyond that is a mystery.
"I don't know," UFC president Dana White said Diaz's future, per TMZ Sports. "I never know that either. We'll take it one fight at a time.
Diaz will face Lawler Saturday at UFC 266, the first match for the 38-year-old since a no contest against Anderson Silva in January 2015.
Even White doesn't know how the veteran fighter will fare in his return to competition.
