Pat Beverley opted to undergo arthroscopic knee surgery on Tuesday and is expected to be out for four to six weeks, a person with knowledge of the decision said Saturday.
Beverley had not played since the first preseason game and had met with doctors several times to consider treatment options.
Mike D'Antoni on Friday indicated Beverley could miss the season's first 20 games. Beverley averaged 9.9 points on 40 percent 3-point shooting last year.
Eric Gordon will replace Beverley in the Rockets' starting lineup.
