Blue (shoulder) returned to practice Monday and is expected to play in Sunday's preseason game against the Cardinals.
Although he missed the first two preseason games, Blue was healthy for the first two weeks of training camp, getting plenty of reps along the way. While not much of a pass-catching threat, Blue is a clear favorite to serve as Lamar Miller's top backup for early downs. Jonathan Grimes handled a lot of the passing-down work last year, but he may need to fend off 2015 seventh-rounder Kenny Hilliard in a competition for a roster spot, as rookie fourth-rounder Tyler Ervin is a lock to make the team even if he doesn't earn much of a role.
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.
