Blackmon, 22, was booked into Payne County Jail at 10:22 a.m. CT on Sunday and was released at 12:45 p.m. after posting $1,000 bond. Oklahoma law says aggravated DUI applies to drivers with a .15 or higher blood alcohol level.
An arraignment for Blackmon is scheduled for 1:30 p.m. ET on Monday, according to the Florida Times-Union.
Jaguars spokesman Dan Edwards told The Associated Press the team is aware of the report and is gathering information.
For Blackmon, this is the second time he has been arrested on a DUI complaint. In October of 2010, Blackmon was arrested in Carrollton, Texas after attending a Dallas Cowboys game on Monday Night Football. Blackmon did not have permission to attend the game and was suspended for one game by Oklahoma State head coach Mike Gundy.
In 38 games at Oklahoma State, the 6-foot-1, 207-pound Blackmon caught 252 passes for 3,564 yards and 40 touchdowns. Blackmon left Stillwater after catching 121 passes for 1,522 yards and 18 touchdowns as a junior. The Jaguars traded up with the Tampa Bay Buccaneers to select Blackmon with the No. 5 pick in the 2012 NFL Draft. Blackmon has yet to sign his rookie contract, which is expected to be worth around $18.5 million in fully guaranteed money.
