Cascade County Attorney John Parker charged Leaf 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
If convicted, Leaf faces a maximum prison sentence of 20 years on each burglary charge and five years for each possession charge.
An arraignment has not yet been scheduled. A message left with Leaf's attorney in Great Falls was not returned Friday afternoon.
Leaf is jailed without bond on a 30-day hold while Montana and Texas authorities exchanged information on whether the Montana arrest violated the terms of his probation from a 2010 plea deal in Texas. In that case, Leaf was accused of burglarizing a player's home while he was a quarterbacks coach for Division II West Texas A&M and an investigation turned up that Leaf had obtained nearly 1,000 pain pills from pharmacies.
