ST. LOUIS - St. Louis Blues defenseman Eric Brewer has undergone arthroscopic surgery on his right knee in what the team termed a minor setback for a player rehabbing from two back operations.
Brewer, the team captain, played in 28 games last season before undergoing surgery in December to repair a herniated disc in his back. He had a second back operation in April.
The team said Thursday that Brewer was expected to be sidelined two to four weeks by the latest surgery, performed in Vancouver.
Brewer had a goal and five assists last season.
