The Denver Nuggets confirmed Wednesday that forward Chris (Birdman) Andersen is day-to-day with moderate patellar tendinitis in his right knee.

Andersen has experienced soreness, so underwent an MRI in Denver.

Dr. Steve Traina said the test revealed no structural damage.

Also, guard Anthony Carter is listed as questionable for the Nuggets' game Friday night against the Clippers in Los Angeles.

He has sat out the last two games with a strained left hip.
