OWINGS MILLS, Md. -- The Baltimore Ravens took a major step toward trimming their roster to the league-mandated 53-man limit Friday, when they parted ways with 18 players and placed six on season-ending injured reserve.

The most notable cuts were former Navy star Keenan Reynolds and six veteran players: center Jeremy Zuttah, tight end Larry Donnell, quarterback Thad Lewis, running back Bobby Rainey, cornerback Trevin Wade and wide receiver Griff Whalen.

Reynolds was a long shot entering the preseason finale, and he fumbled a punt return Thursday night, which sealed his fate. A sixth-round pick in 2016, Reynolds has been trying to make the transition from a college quarterback to an NFL wide receiver and returner.

The Ravens cut Zuttah, a former three-year starter, after acquiring Tony Bergstrom from the Arizona Cardinals for a conditional seventh-round pick. The release of Donnell could increase the chances of Vince Mayle making the team.

The players waived were punter-kicker Kenny Allen, linebacker Randy Allen, wide receiver C.J. Board, guard Jarell Broxton, safety Otha Foster, offensive tackle Roubbens Joseph, center Derrick Nelson, long-snapper Taybor Pepper, guard Jarrod Pughsley, running back Lorenzo Taliaferro and offensive tackle De'Ondre Wesley.

The Ravens also officially ended the seasons for running back Kenneth Dixon (knee), guard Alex Lewis (shoulder), linebacker Albert McClellan (knee), offensive lineman Nico Siragusa (knee), receiver-returner Tim White (thumb) and cornerback Tavon Young (knee).

The Ravens need to make 14 more moves to get down to the 53-man limit by 4 p.m. ET Saturday.
