State District Judge William Sowder on Thursday ordered Leach, Texas Tech and their attorneys to complete mediation by Feb. 5. He also placed gag order on the talks.
The university fired Leach on Dec. 30, two days after it suspended him amid allegations he mistreated a player with a concussion. His suit includes allegations of libel and slander and breach of contract.
Leach has denied he mistreated receiver Adam James, who said his coach twice ordered him to stand for hours while confined in a dark place during practice.
