Batum injured his knee in the second quarter of Portland's 101-90 loss to Oklahoma City on Monday. X-rays following the game were negative and an MRI on Tuesday ruled out a serious injury.
Blazers guard CJ McCollum sprained his left ankle during the game against the Thunder and won't play against the Mavericks. Chris Kaman also left the game in Oklahoma City with a sore back.
Portland All-Star LaMarcus Aldridge, who rested a left foot sprain against the Thunder, was listed as probable for the Dallas game.
The Blazers have already clinched the Northwest Division title and a spot in the playoffs.
