Dallas Mavericks coach Rick Carlisle expressed disappointment with Lamar Odom's ongoing absence from the team and bluntly stated that the forward will face scrutiny upon his return, from owner Mark Cuban to the players in the locker room.

Odom will play Saturday night for the Mavs' D-League affiliate in nearby Frisco and then is expected to re-join the Mavs for the first time since Feb. 20 when the team travels to Oklahoma City for Monday's game, Carlisle said.

"When he comes back, we're going to find out very quickly where things are at," Carlisle said during his weekly appearance Friday on the ESPN Dallas 103.3 FM's "Galloway & Co." "He's going to have to show us with his actions and attitude that he's in."

Odom left the Mavs on Feb. 22 to tend to a family matter and missed his fourth consecutive game Friday night when Dallas played New Orleans. He will also miss Saturday's game against the Utah Jazz. Odom left the team to attend to his ill father in Los Angeles, sources told ESPNDallas.com.

The Mavs need Odom's presence off the bench in the midst of nine games in 12 nights, the most grueling stretch of the season. After Friday's 97-92 loss at New Orleans, Dallas has lost a season-high four games and five of six.

"Mark asks a fundamental question of anybody in our franchise: Are they in or are they not in?" Carlisle said. "Our fans want to know that Lamar's in. Our players want to know that Lamar's in. It's not about how many points he's scoring or rebounds; those things are a factor. Our fans, our players want to see the guy playing like his pants are on fire and we haven't seen that so far and that's got to change."

Texas Legends owner and Mavericks president of basketball operations Donnie Nelson confirmed Friday that it was Odom's idea to play with the Legends first.
