An MRI confirmed Monday that Lewis and Ladarius Webb have been lost for the season.
Ravens Coach John Harbaugh announced the diagnosis of a “full tear” of the triceps muscle during his Monday press conference.
Former Ravens head coach Brian Billick told USA TODAY Sports the loss of Lewis is a “huge blow.”
“You don’t take a Hall of Fame player like Ray Lewis out of the heart of the defense and say, ‘Okay we’re going to be fine,’ ” Billick said Monday.
Baltimore is still without linebacker Terrell Suggs, who partially tore his Achilles’ tendon in the preseason and remains on the PUP list.
Lewis is a 17-year veteran and 13-time Pro Bowl selection. He was part of a Ravens team that won Super Bowl XXXV. Lewis had talked about retiring soon so he could watch his son play college level football. It is unknown if he plans to attempt a comeback.
