Ex-Michigan State basketball star Keith Appling -- who led the Spartans to the Elite Eight in 2014 -- was sentenced to 18 months probation, stemming from a heroin arrest back in February.
Cops say the 28-year-old was stopped in Warren, Michigan on Feb. 8th after officers spotted his car weaving all over the road.
After he was pulled over, cops say Appling appeared sweaty and woozy -- so they searched the vehicle, and turned up 19 grams of heroin (about the size of a golf ball) in a sandwich bag.
Prosecutors believe Appling intended to sell the heroin.
