Darryl Stonum, a projected starting receiver and U-M's primary  kickoff returner, spent three nights in jail last month, according to  Washtenaw County court records.
The  junior from Stafford, Texas, was sentenced in 15th District Court in  Ann Arbor and spent June 4-7 in Washtenaw County jail for probation  violations.
The  violations stemmed from an early-morning incident Sept. 28, 2008, when  he was ticketed and later charged for operating a vehicle while visibly  impaired. At the time, the Michigan Daily cited a police report stating  that Stonum, then 18, blew a 0.10 on a Breathalyzer, above the 0.02  limit for a minor to drive.
After  the arrest, Stonum was suspended for one game by coach Rich Rodriguez.  Stonum was arraigned Nov. 19, 2008, and pleaded guilty Feb. 17, 2009.  Sentencing was scheduled for April 8, 2009.
Washtenaw County prosecutor Steve Hiller said Tuesday that it was a normal, if not quick, time line.
According  to court documents, Stonum was sentenced at the April 8 hearing to a  fine, community service and probation. The terms of probation included  substance-abuse education and submitting to random drug and alcohol  testing.
However, he landed back in the Ann Arbor court last month.
From  May 15, 2009, through June 1, 2010, according to court records, he  committed probation violations such as leaving the state without  consent, failing to submit to random alcohol testing nine times in a  63-day span, failing to complete additional alcohol testing and failing  to report for probation on multiple occasions.
At  his June 2 review, according to court documents, 15th District Court  Judge Julie Creal sentenced Stonum to enter jail at 1 p.m. June 4 and be  released at 7 a.m. June 7.
His jail term closed his case June 8.
Rodriguez  declined comment through an athletic department spokesman Tuesday,  citing the Family Educational Rights and Privacy Act (FERPA). Stonum was  not made available by the university, and his attorney did not return a  request for comment.
In  two seasons, Stonum has caught 27 passes for 375 yards and two  touchdowns and returned 40 kickoffs for 1,025 yards and one touchdown.  Last season, he set U-M's single-season kickoff-return record with 39  returns for 1,001 yards.
