(CNN) -- Former Texas Tech Head Football Coach Mike Leach was fired Wednesday for breaching performance provisions in his contract, according to his letter of termination, obtained by CNN.
Leach was fired two days after the school suspended him while it investigated allegations that he mistreated an injured player. Texas Tech, in Lubbock, Texas, has not said whether the investigation was completed, or what the findings were.
The one-paragraph document states that Leach was terminated with cause for breaching Article IV of his contract.
The pertinent article, titled "Performance," in part states, "Coach shall assure the fair and responsible treatment of student-athletes in relation to their health, welfare and discipline. Breach of such rules and standards, whether willful or through negligence, may be subject to disciplinary action and penalties" including termination.
The article also states that Leach, "in the performance of his duties, shall conduct himself at all times in a manner consistent with his position as an instructor of students."
The termination letter is signed by Texas Tech President Guy Bailey.
The letter was handed to Leach's attorney, Ted Liggett, right before a scheduled court hearing to considered Leach's request for a temporary restraining order for the suspension, that would have allowed him to coach Texas Tech in Saturday's Alamo Bowl in San Antonio, against Michigan State.
Leach's firing made the hearing unnecessary.
A court document filed by Texas Tech, arguing against the temporary restraining order, shed some more light onto what transpired behind the scenes.
After allegations surfaced that he made receiver Adam James stand inside a storage shed after James was diagnosed with a mild concussion, Bailey and Athletic Director Gerald Myers met with Leach, the document states.
The university officials handed Leach a letter listing guidelines that the coach would have to follow, including letting a physician decide whether injured players would sit out practice.
It also stipulated that Leach would not retaliate against any injured students.
Leach's actions "may have been injurious to (James') health and served no medical and/or educational purposes," the letter says. "In addition to being unacceptable, if proven, these allegations constitute a breach of your employment contract."
Leach refused to sign the letter, and was suspended as a result, according to court documents.
Texas Tech's response to the restraining order question was signed by Texas Attorney General Greg Abbott.
