Tough luck. But based on post-game reports, the injury isn't as bad as it seems. Bynum himself said that he's going to be able to play. Obviously, he just needs to rest the knee in time for the playoffs.
POR just locked up the 6th seed in the West, while MEM is apparently tanking their final games to drop to 8th for a match-up with the Spurs.
Even if MEM and NOH end up with the same record tomorrow, NOH will be seeded 7th.
