The Ravens activated tight end Darren Waller on Saturday.
Waller had returned to the team earlier in the week on a roster exemption after serving a four-game suspension to start the season. The Ravens did not have to make a corresponding roster move after placing tight end Maxx Williams on injured reserve on Friday.
Waller has played in six career games. He has two receptions for 18 yards and has made three special teams tackles. With Williams and veteran tight end Ben Watson out for the season, Waller will have a chance to be a contributor.
