Leach did not take part in Friday’s session at the team’s training facility in Owings Mills because of what coach John Harbaugh described as back tightness. Ellerbe and Jackson also did not practice, but the reasons for their absences were not disclosed.
Center Matt Birk (back spasms), rookie outside linebacker Courtney Upshaw (bruised right shoulder) and wide receiver Tandon Doss (hamstring) sat out their sixth consecutive practice. Tight end Dennis Pitta (broken right hand), rookie running back Bernard Pierce (hamstring) and linebacker Josh Bynes (undisclosed) did not participate for the fifth straight day.
Wide receiver Patrick Williams (left shin/calf) missed his fourth consecutive practice, while defensive tackle Arthur Jones (hip flexor) did not take part for the third straight day.
Players who are on the physically-unable-to-perform list include offensive tackle Jah Reid (strained right calf) and wide receiver/return specialist David Reed (knee surgery). Five-time Pro Bowl outside linebacker and reigning NFL Defensive Player of the Year Terrell Suggs (torn right Achilles tendon) is on the non-football injury list.
