MINNEAPOLIS – Less than 48 hours from fight night, UFC on ESPN 3 is likely down a fight.

Team Alpha Male’s Vince Murdock announced via his Facebook page that he’s out for his scheduled preliminary card featherweight matchup against Jordan Griffin.

According to the Facebook post, Murdock (12-3 MMA, 0-0 UFC) said his withdrawal was due to the fact he was declared medically unfit to fight by the UFC’s doctors.

“Difficult as it is to say, I must let you know that, I won’t be making the walk this Sat,” the post read in part. “Unfortunately at this time the @ufc requires some more test to clear me medically fit to fight. As difficult as it is for me to write this message, I strongly believe with the required test completed in the coming days I will be cleared to fight.”

Given the short amount of time remaining until fight not, Griffin (17-6 MMA, 0-1 UFC) will not remain on the card. That leaves the card with 12 fights.

UFC on ESPN 3 takes place Saturday at Target Center in Minneapolis. The card airs on ESPN.
