FILE - In this July 27, 2010, file photo, former NFL quarterback Ryan Leaf appears in Holter Lake, Mont. Leaf has been charged with two counts of burglary and two counts of criminal possession of a dangerous drug in court documents filed Thursday but only available on Friday, April 13, 2012.

LUBBOCK, Texas — The Texas prosecutor who brokered a plea deal with former NFL quarterback Ryan Leaf has filed a motion to revoke his probation and will press for prison time.

Randall County district attorney James Farren said Monday that his motion probably will be amended as he gets details about Leaf's latest legal problem. Leaf faces four felonies in Montana after allegedly breaking into a home to steal prescription painkillers, then robbing a second home after being released from jail.

Leaf is likely to face the Montana charges first. He was given 10 years' probation in Texas in 2010 after being accused of burglarizing a player's home while he was a coach at West Texas A&M. An investigation found he obtained nearly 1,000 pain pills from area pharmacies in an eight-month span.
