The Ravens already brought up tight end Daniel Brown earlier this week and Darren Waller is finished serving his four-game suspension.
Waller returned to the practice field earlier this week for the first time in about a month, joining his teammates and coaches following a suspension for violating the NFL's substance abuse policy.
