Indiana Pacers center Andrew Bynum won’t be joining his squad in New York tonight, after swelling in his right knee caused the medical staff to drain it. Bynum admits that the amount of fluid taken out freaked him out a bit. From the team website:

“The knees are still swollen so he’s going to stay behind to get some work in here and some treatment here,” Pacers coach Frank Vogel said following Tuesday’s practice. “We’ll see where he’s at when we get back.”

Bynum, who was in practice gear but didn’t participate on Tuesday, admitted there’s some concern for his recent setback. After scoring 15 points and grabbing nine rebounds in exactly 20 minutes of work Saturday night in Detroit, Bynum has experienced significant swelling in his right knee to the point where he underwent an MRI and had it drained Monday afternoon.

“This one is a little concerning for me because it caused a lot more fluid,” he said. “I haven’t had that much fluid in there since like the (2010) Boston Finals in L.A.”

“It’s not fun,” Bynum added. “It is what it is at this point.”

Doctors analyzed the MRI Tuesday morning, according to Bynum, and he expects to know more Tuesday afternoon.

“[It's] not really disappointing at all, to be honest,” (Vogel) said. “We knew he was going to be in and out of the lineup. He’s got some problems with his knees, we’re well aware of that, and we’ll be excited with what he can give us when he’s in there.”
