It looks like there’s more to Tai Wynyard’s absence than just his back injury.
Kyle Tucker from SEC Country confirmed with a UK spokesman that Wynyard has been suspended from the team for a violation of team rules until further notice.
Tucker did make sure to add that Wynyard’s back injury is still serious enough that, even if Wynyard wasn’t suspended, he’d still be unable to play with this issue.
This would explain why Wynyard was previously seen on the UK bench while recovering from his back injury but has been absent from it in recent games.
