Andrew Bynum is contemplating whether to undergo a second arthroscopic procedure on his right knee.

The surgery would clean out loose cartilage and almost certainly rule Bynum out for the remainder of the 2012-13 season.

Bynum practiced on Friday and acknowledged that his season might in fact be over.

"Now it's getting a little late, so I really don't know," Bynum said when asked if he were considering sitting out the final two months of the Sixers’ season. "I played in one scrimmage and [I have] a four- to five-day setback,"

Bynum said. He added that he is "just getting treatment and trying to push the fluid out" of his knee.

"I still think I can play," Bynum said, "but like I said, the season is short."
