The Calloway County Circuit Clerks office says Jackson will begin serving jail time immediately. The wanton endangerment charges are downgraded from initial charges of assault.
Formal sentencing is scheduled for October 22 at 8:30 am.
Police say Jackson used his car to strike two people Sept. 9 in the parking lot of the Walmart Supercenter in Murray. The 20-year-old Jackson was expected to be a starting guard for the Racers this season.
