MISSOULA — Jordan Gregory, a graduate assistant with the University of Montana’s men’s basketball team and former Grizzlies’ standout player, was arrested early Sunday morning by the Missoula Police Department for allegedly driving under the influence.

The 27-year-old was booked into Missoula County Jail on Sunday at 2:51 a.m. after being arrested and charged with aggravated DUI. He posted a bond of $1,085. Details of the arrest, including where it took place, were not available Monday.

“We are aware of the incident involving Jordan,” UM athletic director Kent Haslam told MTN Sports on Monday. “He is still a graduate assistant with the basketball program, but will not be with them this week when they play at Idaho State and Weber State. What happens beyond that is still to be decided.”

In the state of Montana

, an aggravated DUI differs from a DUI when at least one additional factor comes into play. Those factors are as follows:

• Alcohol concentration is at least two times the legal limit of .08;
• the person is under the order of a court or the department to equip any motor vehicle the person operates with an approved ignition interlock device;
• the person’s driver’s license or privilege to drive is suspended, canceled, or revoked as a result of a prior violation;
• the person refuses to provide a breath sample …; or
• the person has one prior conviction or pending charge for a violation of vehicular homicide while under the influence, negligent vehicular assault, DUI …”

Gregory joined the Griz this fall as a grad assistant after a four-year pro basketball career overseas. Gregory was a standout player during his time with Montana and was a three-year starter who scored 1,234 career points and went to two NCAA Tournaments as a player with the Grizzlies.
