Gordon will likely be released by the Browns, NFL.com reports.
As hinted by head coach Hue Jackson, the team no longer has any plans for Gordon, who will enter an in-patient rehab facility instead of returning from his suspension in Week 5. It's unclear how long Gordon will stay in the facility and when/if he plans to play again this season, but he should eventually draw interest around the league, unless he failed a drug test -- in which case he'd likely be suspended yet again.
Caldwell suffered a hamstring injury during the onset of training camp, Nate Ulrich of the Akron Beacon Journal reports.
It's currently unclear whether the hamstring was merely tweaked or if Caldwell has suffered something worse. Either way, there has been no timeline provided for his return. When healthy, the Browns' fifth-round pick will compete for a role out of the slot.
Bryant (chest) has been placed on the injured reserve list and will sit out the entire season, Mary Kay Cabot of Cleveland.com reports.
Entering his eighth NFL season and fourth with the Browns, Bryant was a lock to start at defensive end after a 2015 campaign which saw him record a career-high and team-leading six sacks. The torn pectoral muscle he suffered earlier this month was originally thought to keep him out 4-to-6 months, making November the soonest possible return date. Rather than push his recovery in the hopes of a return the team decided it best to shut him down for the season. Carl Nassib appears first in line to replace Bryant, but John Hughes and Dylan Wynn could see some extra snaps as well.
Dixon left Saturday's preseason matchup with an apparent chest injury and is questionable to return, Jonathan Jones of the Charlotte Observer reports.
In his NFL debut last week, Dixon tallied three tackles against Baltimore. The Washington product has taken reps at both cornerback and safety for Carolina in the early going, but with a lot of uncertainty surrounding Dixon and his injury, it remains to be seen if he'll be able to squeak onto the roster by preseason's end.
Johnson (Achilles) was placed on the Panthers' reserve/NFI list on Monday, Steve Reed of the Associated Press reports.
Johnson also began training camp on the active/NFI list after undergoing offseason surgery to repair an Achilles injury suffered last season with the Patriots. Although no timetable was provided for his return, Johnson could theoretically resume playing after the first six weeks of the regular season.
