Gillmore suffered a hamstring injury during Friday's practice and will undergo an MRI to assess the damage, Jamison Hensley of ESPN.com reports.
At this point the severity of Gillmore's hamstring injury is unknown, while his status will continue to be monitored upon the results of his MRI. The Ravens' tight end corps is a bit crowded with Ben Watson, Maxx Williams, and Dennis Pitta alongside Gillmore, so an injury could prove costly regarding playing time early in the season.
Dixon (knee) suffered a Grade 1 sprain of his MCL, NFL.com's Ian Rapoport reports.
A Grade 1 sprain is the least severe variety, but with plenty of time remaining in training camp, the Ravens have no reason to rush Dixon back onto the practice field. While the rookie could conceivably return as soon as next week, a longer absence wouldn't necessarily be major cause for concern. Dixon is expected to compete for a role in a Baltimore backfield that also includes Justin Forsett, Javorius Allen, Terrance West and Lorenzo Taliaferro (knee). Dixon, Forsett and Allen are seemingly locks to make the final roster.
Waller has been suspended four games for violating the NFL's substance abuse policy.
Waller will be able to stay with the team through training camp and the preseason before serving his suspension once the season begins. In six games as a rookie last year, he recorded just two receptions for a total of 18 yards, though he did have a greater impact on special teams, where he was a gunner. He'll look to improve on his offensive numbers from last season once his suspension is complete.
Boyle has been suspended for the first 10 games of the 2016 campaign due to a violation of the NFL's policy on performance-enhancing drugs, Jeff Zrebiec of the Baltimore Sun reports.
Boyle was utilized sparsely as a rookie in 2015, hauling in 18 balls for 153 yards over the course of 11 games. However, he received his first suspension related to PEDs on Dec. 7 and subsequently missed the final four contests of the season. With Boyle out of the picture for most of next season, the Ravens rely upon Crockett Gillmore (back) and Maxx Williams to man tight end.
Bryant was never under consideration of being cut by the Steelers despite his recently imposed year-long suspension, the Pittsburgh Tribune-Review reports.
Bryant's multiple violations of the league's substance abuse policy triggered a minimum one-year suspension from the league, but the Steelers never considered releasing him, according to general manager Kevin Colbert. Instead, Pittsburgh will hope Bryant makes the necessary changes to his life to get reinstated next year, when he would have two years remaining on his contract with the team. With Bryant suspended, Steelers receivers Markus Wheaton and, more specifically, Sammie Coates, will be looked upon to take advantage of their increased opportunities this season.
