Tyron Woodley is demanding Colby Covington issues a public apology for cracking jokes about Matt Hughes' near-fatal train collision accident after his fight on Saturday ... calling Colby a "disgrace."
"That ain't funny," Tyron told us in a scathing attack aimed at the welterweight star ... "That ain't a joke. [Matt Hughes] is blessed to even be here, no matter how he got on the tracks."
Of course, Matt -- a UFC Hall of Famer -- was hospitalized in 2017 when a train struck his pickup truck in Illinois.
