The Ravens practiced Tuesday for the third consecutive day without Austin Howard, which likely means that the newly signed offensive tackle will not be available in the preseason opener against the Washington Redskins on Thursday at 7:30 p.m. at M&T Bank Stadium.
Howard agreed to a three-year, $16 million contract with the team Friday, but has yet to make an appearance on the field. The former Oakland Raider underwent surgery in January to repair a torn rotator cuff and a torn labrum in his left shoulder.
Other players sitting out of practice are cornerbacks Maurice Canady (torn cartilage in knee), rookie Marlon Humphrey (undisclosed) and Sheldon Price (unspecified), wide receivers Breshad Perriman (right hamstring tightness) and Kenny Bell (hamstring), running back Kenneth Dixon (torn meniscus in left knee), quarterback Joe Flacco (back), left guard Alex Lewis (unspecified) and rookie guard Nico Siragusa (torn ACL, MCL and PCL in left knee).
Cornerback Tavon Young (torn ACL in left knee) is on the team's physically unable to perform list.
Cornerback Brandon Boykin, who did not practice Monday, returned to Tuesday's session.
