Portland guard Damian Lillard has a sprained right knee and will be sidelined Wednesday when the Trail Blazers play a win-or-else Western Conference first-round game against the Los Angeles Lakers. The Blazers trail the best-of-seven series 3-1, and now will play without their leading scorer. Lillard got hurt while driving to the basket and drawing a foul with 7:16 left in the third quarter of Monday's game against the Lakers.
