The Ravens may not be done adding to their roster.
The team had veteran guard Eric Steinbach and some unnamed outside linebackers in for workouts on Tuesday, and Head Coach John Harbaugh said that they will continue to look for additional pieces.
"We are always looking for players," Harbaugh said. "We're always looking to upgrade."
Steinbach, 32, would give the Ravens another veteran in an already-crowded competition for the starting left guard spot. The veteran lineman is expected to draw interest from some other teams around the league, and it's unclear if the Ravens will end up signing him.
"Eric Steinbach is a heck of a player," Harbaugh said. "I don't know where we stand, but we're going to look for any good player we can at any time."
Steinbach missed all of last season with a back injury, but he has primarily been a durable player throughout his 10-year career. He started all but four games during his eight seasons with the Cleveland Browns (2007-10) and Cincinnati Bengals (2003-06).
If the Ravens sign Steinbach, he would compete with fellow veteran Bobbie Williams, second-year lineman Jah Reid and rookies Kelechi Osemele and Gino Gradkowski. Osemele (back muscle spasms) and Reid (strained calf) missed Tuesday's practice, but Harbaugh said he hopes Osemele returns later this week. He did not provide a timetable for Reid's return.
At outside linebacker, the Ravens could be looking to add some depth following injuries to Terrell Suggs and Michael McAdoo, and the free-agency departure of Jarret Johnson. Harbaugh did not specify who the Ravens had in for a visit.
The team does have some salary-cap space to work with after signing running back Ray Rice to a five-year contract last week. Before signing Rice, the Ravens had previously been right up against the salary cap, but his five-year contract reportedly gives the team about $3.5 million in space.
"If we can create some better competition and put more good players in the mix, with the financial resources that we have, then we always want to do that," Harbaugh said. "You have an opportunity where you have good players who are available and we're going to take a look at them and try to make the roster better any way we can, at any time."
