Smith to take over as defensive coordinator
Texas Tech announced on Thursday that defensive coordinator Matt Wallerstedt has resigned effective immediately for personal reasons, just 16 games into his tenure.
Co-defensive coordinator Mike Smith, a Coronado and Tech graduate, will take over the defense for the rest of the season, Tech said in its announcement.
ESPN.com reported that Wallerstedt was suspected of being under the influence and sent home on Monday from the team’s facility. Tech coach Kliff Kingsbury did not make any of his coaches available to the media Monday, a change from the usual routine.
