The Mavericks have placed guard Michael Finley on the injured list with a sprained right ankle.

Finley was injured in the third quarter of Tuesday night's game at Orlando on a drive to the basket.

Finley is required to miss five games for being placed on the IL, but coach Don Nelson indicated the absence could be longer.

"He's pretty sore, and he's going to miss some time," Nelson told the Dallas Morning News. "I'd say a lot more than a little."

To replace Finley on the roster, the Mavericks activated guard Dan Dickau from the injured list.
