OWINGS MILLS, Md. -- The Baltimore Ravens are without 14 players for Monday's practice, which is their second-to-last one for training camp at the team facility.

There are only two starters out: left guard Kelechi Osemele (foot) and cornerback Lardarius Webb (hamstring). Ryan Jensen is filling in for Osemele, and Kyle Arrington is in Webb's spot.

Jensen is working with the first team because of the run of injuries at guard. Top backups John Urschel and Robert Myers are dealing with concussions.

At wide receiver, Kamar Aiken (undisclosed) and Marlon Brown (back) returned but Michael Campanaro (undisclosed) is out for the first time in this year's training camp. First-round pick Breshad Perriman (knee) is missing his 12th straight practice after injuring his knee on the first day of camp (July 30).

The other players not present at the start of practice: OT Jah Reid, TE Allen Reisner (ankle surgery), CB Asa Jackson, SS Matt Elam (bicep), LB Steven Means (undisclosed) and DE Brent Urban (bicep).

Tight end Dennis Pitta (hip) and free safety Terrence Brooks (knee) are on the physically unable to perform list.
