The Rams signed Presley to the practice squad Monday, Zach Edwards of the team's official site reports.
Presley was waived by the Rams on Sunday despite a productive preseason, finishing with 14 catches (on 17 targets) for 125 yards and a touchdown while returning two kickoffs for 59 yards and one punt for 11 yards. He's back with the Rams on the practice squad and could be elevated to the active roster if the team needs a pass catcher and special-teams contributor on game day.
