The Baltimore Ravens signed first-round pick Ronnie Stanley to a four-year, $20.4 million deal on Friday.

Stanley, the No. 6 overall pick, is the fourth top-10 pick to sign. He received a $13 million signing bonus.

The Ravens will start Stanley at either left tackle or left guard, depending on what happens with starting left tackle Eugene Monroe.

Baltimore also waived four players: wide receiver Marlon Brown (failed physical), defensive backs Jermaine Whitehead and Nick Perry, and defensive end Nordly Capi.

Brown's production significantly declined after 2013, when he tied a Ravens franchise rookie record with seven touchdown catches. He had only 14 receptions for 112 yards last season.
