Left tackle Patrick Mekari, defensive tackle Michael Pierce and outside linebacker Justin Houston were among the six Ravens missing at practice Wednesday.

Mekari (ankle), Pierce (arm) and Houston (groin) left Sunday’s win over the New England Patriots and did not return. Coach John Harbaugh indicated Sunday that Mekari and Houston are dealing with minor injuries, though Pierce’s timetable for his recovery is uncertain. The Ravens host the Buffalo Bills on Sunday.

Also missing Wednesday were cornerbacks Marcus Peters and Jalyn-Armour Davis and defensive lineman Calais Campbell, who typically gets a day off to start the week of practice.

Newly signed outside linebacker Jason Pierre-Paul made his practice debut Wednesday, while cornerback Daryl Worley, who was released from the 53-man roster Tuesday, was back on the field as a practice squad member.
