Head Coach John Harbaugh said Monday that the Ravens plan to give more opportunities to young players the rest of the season, and on Tuesday the team added a young cornerback and running back to the active roster.
They were among seven overall transactions on the day.
Cornerback Jumal Rolle and running back Terrence Magee were both promoted from the practice squad to the active roster.
To make room for them, the Ravens placed veteran defensive end Chris Canty (torn pectoral) on injured reserve, and cut running back/ return specialist Raheem Mostert. The Ravens also signed quarterback and cut Bryn Renner to make room. The Ravens also added offensive tackle Marcel Jones to the practice squad.
Rolle, 25, was an undrafted prospect in the 2013 draft, and he's bounced around five teams since that point. He opened this year with the Houston Texans, but they cut him last month and the Ravens signed him to the practice squad on Nov. 20.
The 6-foot cornerback has shown the coaching staff enough to earn a chance to get on the field.
"Jumal Rolle is going to step up and get a chance," Harbaugh said.
The decision to promote Rolle coincides with Harbaugh's announcement Monday night that the Ravens want to use veteran defensive back Lardarius Webb in more of a free safety and nickel cornerback role. Moving Webb inside will allow the Ravens to get Rolle and rookie cornerback Tray Walker on the field.
"We have some young guys we can put outside. So, we're going to pull the trigger, put those guys outside, put Webby in there where he belongs, let him play the nickel, let him play free safety," Harbaugh said. "He looks great playing free safety back there."
Magee, 22, replaces Mostert on the active roster. Magee is an undrafted rookie who has bounced between the 53-man roster and the practice squad throughout this season, and has appeared in two games in special-teams roles.
Mostert spent seven games on the active roster as a kickoff return specialist. The Ravens could give wide receiver Kaelin Clay a chance to return kickoffs now based on how well he has performed in punt return duty.
