Mavericks coach Avery Johnson will personally work out former All-Star Shawn Kemp in Houston today, the Fort Worth Star-Telegram is reporting.

With the loss of Keith Van Horn to a broken hand, the Mavs are in the market for a backup to Dirk Nowitzki.

Kemp, 36, has been working out in Houston in an attempt to make a comeback. He retired after the 2002-03 season with Orlando, citing weight issues. He's reportedly lost about 50 pounds from his high of 320 pounds.

Even if the Mavs aren't granted the hardship exception to sign a 16th player, Kemp could still be in the plans. Waiving one of the 15 on the roster -- rookie Rawle Marshall is the probable candidate -- would free up a spot.
