UFC champ Tyron Woodley watched the TMZ Sports video of Nick Diaz going off about a possible fight for the belt -- and says one thing is clear to him ... Nick's an idiot.
Woodley joined the guys on the "TMZ Sports" TV show (airs Monday night on FS1) and clapped back at Diaz ... saying he was trying to COMPLIMENT the guy as a great fighter to set up a big money fight.
But Woodley says Diaz took the message the wrong way -- "He made no sense."
"It just shows you his I.Q. outside of fighting is not extremely high."
Woodley says Diaz may have blown his shot at the title -- and hinted that he's closer to locking up a fight with Georges St-Pierre.
There's A LOT more in the full interview tonight on FS1.
