Nick Diaz is one of the biggest names in MMA and is fresh off an 18-month suspension for testing positive for marijuana (surprise!). Yet he still doesn’t have a return fight booked in the UFC yet, and wouldn’t be able to compete in one anyway, until he pays an outstanding fine.

Diaz was hit with a $75,000 fine to go along with his suspension (which was originally an outrageous five years long, before UFC lawyers appealed on his behalf). However, Damon Martin of FOX Sports is reporting that Diaz hasn’t bothered to pay that and technically remains suspended until he does.

Diaz tested positive for marijuana after a January 2015 fight against Anderson Silva. He lost via decision, but the result was later overturned into a No Contest when Silva failed his own drug test, for performance enhancers. The Nevada State Athletic Commission tried to make an example of Diaz by banning him for five years, a move that may have effectively ended his career. After a huge outcry about the Commission overstepping its own boundaries, the suspension was eventually reduced to 18 months.

If Diaz wants to fight again, though, he’ll have to pony up the cash sooner or later. Maybe he can get a loan from his younger brother Nate, who just cashed two huge paychecks from his fights with Conor McGregor. The second fight alone earned him a cool $2 million disclosed payday.
