That involved inserting metal hardware into the ankle to aid the healing process for the 6-foot-5, 305-pounder who got injured in the first preseason game against the Atlanta Falcons at the Georgia Dome.
McBean, 28, hasn't been placed on injured reserve, but the recovery process typically takes two to three months before the pins and screws are removed with a full recovery ranging from four to six months.
Anderson also did the surgery for Ravens outside linebacker Terrell Suggs, who partially tore his Achilles tendon in late April and is expected to miss at least the majority of the season.
McBean, who's suspended for the first three games of the NFL season for a violation of the NFL's performance-enhancing drug policy when he was playing for the Denver Broncos, was signed to a one-year, $1.214 million contract this spring. The contract isn't guaranteed and didn't include a signing bonus.
Because his suspension is without pay, McBean will be docked a total of $214,000. His weekly game checks are $71,411.
