Suspended Jacksonville Jaguars receiver Justin Blackmon pleaded guilty Wednesday to a charge of driving under the influence in Oklahoma.
Carter County filed documents Thursday saying the 26-year-old will be sentenced on June 8.
Authorities arrested the former Oklahoma State standout in December after an officer said he smelled alcohol in Blackmon's vehicle. The report says Blackmon failed a field sobriety test and refused a breath test.
Blackmon's attorney did not immediately return a call requesting comment.
Blackmon had previously pleaded no contest to misdemeanor marijuana possession. Authorities say police in an Oklahoma City suburb stopped Blackmon in July 2014 for a traffic violation and discovered three grams of marijuana inside his car.
Blackmon was suspended in 2013 for repeated violations of the NFL's substance-abuse policy.
