Butler County Sheriff Richard Jones said after the 39-year-old Blount retrieved the package from a Liberty Township address on Thursday, deputies followed him to his home nearby and arrested him. Jones said officers found another 11 pounds of marijuana inside Blount's house.
Blount was charged with felony drug possession. He was released from custody on $10,090 bond.
The center on Cincinnati's Final Four team in 1992, Blount went on to an 11-year NBA career that included stints with the Chicago Bulls, L.A. Lakers, Cleveland Cavaliers, Phoenix Suns, Philadelphia 76ers and Toronto Raptors.
His phone is unlisted and court officials couldn't say whether he has an attorney.
