James, an ESPN analyst, threatened to sue the university if it didn't investigate Leach's treatment of his son, Adam, who was recovering from a concussion.
This according to a memo by Texas Tech attorney Ronny Wall, who wrote that on Dec. 20, James "indicated that litigation could ensue if TTU did not proceed to investigate Leach for the improper treatment of an injured student-athlete."
"The threat did not appear to be an idle threat as the parent expressed genuine concern for the health and well-being of his injured child, as well as other student-athletes."
Wall's memo was obtained by the Lubbock Avalanche-Journal in response to an open records request.
Scott McLaughlin, a spokesman for James, said no threat of legal action was made at any point.
