Waller was suspended for the first four games of last season for his initial violation and now faces a year out of the league for his latest. The 24-year-old will be allowed to participate in preseason practices and games, but his punishment will begin once the regular season does. A sixth-round pick in 2015, Waller caught 10 passes for 85 yards and two touchdowns last season. His absence -- which follows Dennis Pitta's most recent hip injury and subsequent release -- figures to allow Nick Boyle to see more action behind Ben Watson, Crockett Gillmore and Maxx Williams at tight end in the buildup to this season.
Waller was one of three tight ends on the team dealing with an injury, but it does not appear to have been a serious issue. His participation in minicamp seems to indicate he will be healthy entering training camp. He figures to compete to make the final roster and provide depth at tight end.
Waller (undisclosed) was sidelined during OTAs, ESPN's Jamison Hensley reports.
Waller joins a long list of Ravens tight ends that are dealing with injuries as Ben Watson (Achilles), Crockett Gillmore (shoulder) and Maxx Williams (knee) weren't available for OTAs either. However, it isn't clear what kind of injury he's dealing with or if he'll be back in time for training camp.
