Andrei Kirilenko injured his left leg in the second quarter of Monday's game against the Blazers and went to the locker room. The trainers were looking at either his lower quad or the upper part of his knee and he walked back to the locker room under his own power. AK-47 has dealt with a slew of back injuries, but this is his first knee problem in the NBA since 2011. We'll update you when we know more.
