Lakers' center Andrew Bynum, expected to be sidelined until at least the middle of March, expressed both disappointment and optimism in his first interview since injuring his left knee.

"It's serious because I'm going to miss two months. At the same time, it's not because it's nothing that's going to affect my future," Bynum told reporters shortly before Thursday night's game against the Phoenix Suns.

"I can't do anything. It's terrible," Bynum said. "I have to sit on the couch all day. I have to take it one step at a time. I think I'll have about 10 games when I come back. If I can come back before that, it's great. It's going to take me a little bit of time to get into my rhythm."
