Lee (hamstring) did not participate in practice Friday, Kevin Patra of NFL.com reports.
Lee appears to be dealing with a minor hamstring injury, while it's not expected to keep him sidelined for an extended period of time. He's projected to be the third option in the Jaguars' rising receiving corps behind Allen Robinson and Allen Hurns, with Blake Bortles leading the aerial attack.
Yeldon (ankle) was held out of Friday's practice, Kevin Patra of NFL.com reports.
Yeldon did not take part in practice Friday after being seen limping around the locker room Thursday, apparently due to an issue with new cleats. Yeldon's issue doesn't appear to be serious and he could be back at practice in no time. He still figures to compete with Chris Ivory throughout training camp for touches in the Jaguars' backfield.
Colvin has been suspended for the first four games of the 2016 regular season for violating the league's policy on performance enhancing substances, The Florida Times-Union reports.
Colvin will remain eligible to participate in offseason and preseason activities, but will be sidelined for four games once the regular season kicks off. With Colvin out, offseason signing Price Amukamara becomes increasingly likely to start opposite Davon House at cornerback to begin this season.
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.
Geathers injured his foot while working out in the offseason, ESPN reports. "Unfortunately, he has a foot injury. He's doing well. He's three weeks into that. He'll be week to week," head coach Chuck Pagano said.
It doesn't sound like a long-term injury, but his return date isn't clear. T.J. Green is the leading candidate to start opposite Mike Adams at safety if Geathers isn't ready for the start of the regular season.
Jones will be suspended for the first four games of the 2016 season for violating the NFL policy on PEDs, Ian Rapoport of NFL.com reports.
Jones missed the entire 2015 season due to torn ligaments in his ankle and did not participate in spring practices. He may have been sidelined to start the season even without the suspension, but this still hurts Indy's depth on the defensive line.
