Marc Stein of ESPN has learned that Jazz forward Andrei Kirilenko could miss up to a month with a sprained MCL in his right knee and is expected to be placed on the injured list Tuesday.

Kirilenko, off to a strong start through 14 games, was injured Saturday when Spurs guard Beno Udrih fell backward into Kirilenko's right knee.

The fourth-year veteran from Moscow is averaging 14.8 points, 7.2 rebounds and 4.4 blocks this season.
