NEW YORK -- Former NBA point guard Jason Williams will miss six to eight months after suffering a knee injury in the opening game of the Big3.

Williams, the flashy point guard nicknamed White Chocolate, went down late in the game. His 3 Headed Monsters gave up the lead once he went out. They were one point from losing, but Rashard Lewis made his basket and free throw to edge the Ghost Ballers 62-60.

The 41-year-old Williams' injury shows the risk of relying on players well past their primes, as his was one of two injuries to occur in the first two games.

Corey Maggette, also injured in the opening week of Ice Cube's three-on-three league of former NBA players, had surgery for a leg injury. There is no timetable for his return.

The injuries were announced Wednesday during a conference call with Cube and Big3 co-founder Jeff Kwatinetz, who also detailed a couple of rules changes starting with this weekend's game in Charlotte, North Carolina.

Games will be played to 50 points, instead of 60, with halftime coming when the first team reaches 25 points. Cube said that would help the four games per day move more quickly.
