Farren said he hoped to file a formal request for extradition Wednesday. Farren said his understanding with Montana authorities is that Leaf would agree to waive extradition and would return to Texas soon to allow a judge there to decide what to do about Leaf's probation violation.
Leaf's attorney, Kenneth Olson, said that his family members fear he may take his life if his addiction problems aren't fixed.
He said Leaf's problems with pain killers began years ago and persist despite past treatment efforts. Olson said Leaf relapsed after he went through chemotherapy for a brain tumor.
The defense attorney said the more intensive lockdown treatment offered by the program in Lewistown could help.
''If he is successful in treatment and dedicates himself to helping others, he has great potential to do that,'' Olson said. ''The fact is Ryan is at a very serious crossroads in his life.''
Leaf admitted that he broke into a home in Cascade County, Mont., on April 1. He then admitted that a few days earlier, on March 28, he illegally possessed oxycodone that was not prescribed to him.
He pleaded guilty last month to one count each of felony burglary and criminal possession of a dangerous drug. Under the agreement, Cascade County prosecutor John Parker agreed to dismiss two other counts of burglary and drug possession.
Prosecutors say the investigation into Leaf began in March, when Great Falls postal workers tipped the Central Montana Drug Task Force that Leaf was receiving frequent packages and paying more than $500 cash on delivery for each.
In his statement Tuesday, Leaf said the prison time would be ''bliss'' for friends, family and everyone else tired of hearing about his drama.
The former quarterback dismissed his attorney's assertion that NFL injuries are to blame for his problems, saying he has simply been ''lazy and dishonest.''
