The NFL has reinstated tight end Darren Waller after a year-long suspension.
Waller reported to training camp Monday after the league approved his application for reinstatement.
To make room for Waller on the 90-man roster, the Ravens released undrafted rookie receiver Jaelon Acklin. Waller hasn't taken the field yet, however.
The talented tight end was suspended last June for violating the league's policy on performance-enhancing drugs. It was Waller's second suspension for violating the policy since entering the league as a sixth-round pick in 2015.
Waller, 25, has been open in the past about his marijuana use in college and the NFL. He was also suspended during his career at Georgia Tech for failed drug tests.
The 6-foot-6, 255-pound tight end has played 18 games during his NFL career. He has 12 catches for 103 yards and two touchdowns. He had also emerged as a strong special teams player.
Waller will enter a crowded competition at tight end after the Ravens drafted Hayden Hurst and Mark Andrews this year in the first and third rounds, respectively. Baltimore also still has Nick Boyle, Maxx Williams and Vince Mayle, who were all on the 53-man roster last season.
