Ravens defensive end Ryan McBean broke his left ankle Thursday night against the Atlanta Falcons at the Georgia Dome, a league source confirmed.
It's a fracture dislocation and it will require surgery, according to the source.
McBean is scheduled to visit Dr. Robert Anderson on Monday for further examination.
Anderson is the noted Charlotte, N.C. orthopedist who performed Pro Bowl outside linebacker Terrell Suggs' surgery to repair a partially torn Achilles tendon.
He's regarded as the top doctor of choice for NFL players dealing with foot and ankle injuries.
McBean, 28, is suspended for the first three games of the NFL season for a violation of the NFL's performance-enhancing drug policy.
The Ravens signed McBean to a one-year, $1 million contract this spring.
The former Oklahoma State standout recorded 33 tackles and four sacks last season, playing in every game for the Denver Broncos.
The 6-foot-5, 305-pounder has 77 career tackles and four sacks in 46 NFL games.
McBean was selected by the Pittsburgh Steelers in the fourth round of the 2007 NFL draft.
