Dirk stays home to rest

Mavericks forward Dirk Nowitzki did not practice Saturday, instead staying home to rest after a hard collision with Houston Rockets forward Carl Landry Friday night gashed open Nowitzki's right elbow, requiring three stitches. Nowitzki's elbow crashed into Landry's mouth.

Nowitzki left the game at the 9:28 mark of the second quarter and did not return. Reports from the locker room were that pieces of Landry's teeth -- he broke five and had to go to the hospital -- were lodged underneath Nowitzki's skin.

The Mavs' leading scorer remains questionable for Sunday's 6:30 p.m. game against LeBron James and the Cleveland Cavaliers. Dallas is looking to avoid consecutive losses and a fifth home loss. They lost nine all last season.
