The official, who asked not to be named, said he believes the contract is for five years.
The contract has not been signed and no press conference has yet been scheduled, the official said.
CBS Sports reported the deal will make Leach the third-highest paid coach in the Pac-12. USA Today earlier this month published the top two coaches as Oregon's Chip Kelly $2.8 million; and
Cal's Jeff Tedford, $2.3 million, in total compensation.
Leach, 50, compiled an 84-43 record at Texas Tech from 2000-09. All 10 of his teams posted winning records and played in bowl games.
Leach was fired prior to the 2009 Alamo Bowl after disputes with the school. Leach has a lawsuit pending against Tech.
Leach replaces Paul Wulff, who was fired Tuesday after posting a 9-40 record in four years at WSU.
