Veteran Jimmy Smith was ruled out and four other Baltimore cornerbacks are listed as questionable for Sunday’s home game against the Jacksonville Jaguars.

Smith will miss the contest due to rib and shoulder injuries. Star corner Marcus Peters (calf) is questionable, along with Anthony Averett (ankle), Davontae Harris (ankle) and Tramon Williams (thigh).

Peters, who was injured during Monday’s game against the Cleveland Browns, didn’t practice this week. He has missed just three games in six NFL seasons.

Marlon Humphrey, who leads the NFL with eight forced fumbles, is the team’s lone healthy cornerback.

“We’re just learning as we go,” Ravens coach John Harbaugh said of the dilemma involving the cornerbacks. “It’s only Friday, so we’ll see when we get there.”

The Ravens (8-5) could promote Pierre Desir off the practice squad or activate Terrell Bonds (knee) from injured reserve.

Also, linebacker Kristian Welch (foot) was ruled out of the contest. Starting defensive ends Calais Campbell (calf) and Derek Wolfe (neck/back), safety Anthony Levine Sr. (abdomen), tight end Luke Willson (hip), and defensive tackle Broderick Washington (concussion) are also listed as questionable.
