Texas Tech has released a signed, sworn affidavit from an athletic trainer who says former coach Mike Leach instructed him to "lock" receiver Adam James in a dark place and that he disagreed with Leach's treatment of James after the player was diagnosed with a concussion.

According to his affidavit, taken by representatives of the university on Dec. 21 and signed on Jan. 1, trainer Steve Pincock did not agree with the treatment and said he knew of no other player ever being placed in a similar room.

In releasing the affidavits from Pincock and treating physician Dr. Michael Phy, the university said, "After coach Leach's conflicting recent media accounts of the treatment of James, the university asked witnesses to sign affidavits attesting to their original statements."

Phy told university officials in his affidavit that James "may not have been harmed," but he "considered this practice inappropriate, and a deviation from the medical standard of care."

Leach was fired by Texas Tech on Wednesday, two days after he was suspended by the university as it investigated James' allegations of mistreatment. James is the son of ESPN college football analyst Craig James.
