In the days following Tennessee’s difficult double-overtime loss to Texas A&M on Saturday, senior DT Danny O’Brien was unexpectedly dismissed from the team. The only reason given for O’Brien’s dismissal was an unspecified violation of team rules.

On Thursday, a reason was given for O’Brien’s dismissal via Knoxville’s The Sports Animal host Jimmy Hyams:

O’Brien was suspended for the Oklahoma game in 2015 after an unspecified violation of team rules.

The senior had eight tackles, three for loss, so far in 2016.
