Colvin (suspension) returned to practice Wednesday, Ryan O'Halloran of the Florida Times-Union reports.
Colvin was dealing with an ankle injury and had been sidelined since the team's preseason opener. He was back on the field Wednesday and should be available for Saturday's matchup with the Buccaneers. Colvin is suspended for the first four games of the regular season for taking performance enhancing substances, but he should be back to full strength by then.
Blackmon (suspension) was handed a one-year suspended sentence and probation Wednesday, stemming from a misdemeanor DUI, the Florida Times-Union reports.
Taken fifth overall in the 2012 NFL Draft by the Jaguars, Blackmon hasn't played in an NFL game since being suspended indefinitely back on Nov. 1, 2013 for a violation of the league's substance abuse program. Though he remains listed on Jacksonville's roster, the the 26-year-old wideout seems increasingly unlikely to play for the team again.
