UPDATE 2: According to ESPN:
Texas Tech fired defensive coordinator Matt Wallerstedt on Thursday after the coach was suspected of being at the school's football building while under the influence of a controlled substance, sources told ESPN.com.
UPDATE 3: ESPN has updated their story to now say that it was an "unknown" substance rather than a "controlled" substance.
