Men’s bantamweight champion Garbrandt is slated to defend his title against his former Team Alpha Male colleague in the co-main event of UFC 213, which takes place at the T-Mobile Arena in Las Vegas on July 8.
However, a back injury to the Ohio native has brought about the cancellation of the eagerly-anticipated contest.
Garbrandt, who claimed the men’s 135lbs crown last December at UFC 207, broke the news on Twitter earlier this evening.
“Flying to Germany tomorrow for my second back procedure in less than 3 months, rest easy T.J Dillashaw your time will come,” he tweeted.
“I tore my back over two months ago and did stem cells that didn’t heal my back as I was told, now off to Germany for another procedure!”
The UFC brass have yet to announce the cancellation of the contest, which was supposed to headline the second card of International Fight Week.
The cancellation of Gabrandt vs. Dillashaw will no doubt be announced by the UFC chief.
