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 was reportedly arrested Saturday in Ardmore, Oklahoma for driving under the influence, the Florida Times-Union reports.
Blackmon, who hasn't played since October of 2013, remains under contract with the Jaguars, but it seems increasingly unlikely that he'll play for the team again. At this time, the 25-year-old wideout remains under an indefinite suspension from the NFL.
