A few days ago, Houston Rockets guard Patrick Beverly decided to undergo surgery on his ailing knee.

The feisty point guard was initially expected to miss three weeks before resuming basketball activities. However, in a recent article by Jonathan Feigen for the Houston Chronicle, that timetable had just got extended.

Rockets guard 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.

The Rockets have yet to announce Beverly's surgery, but coach Mike D'antoni has already said he expects Beverly to be out for the season opener.

Beverly has been sidelined since the very first preseason game, and gathered several opinions before making his decision on the surgery.

Eric Gordon will replace Beverly in the starting lineup, and the team is expected to be more than twenty games into the season before Beverly's return.
