The struggling Dallas Mavericks' backcourt is in flux and they have added a veteran with a championship pedigree to try to help stabilize it.

Derek Fisher is expected to make his debut with the club Saturday night when the Mavericks host the Detroit Pistons trying to avoid their first four-game skid.

Fisher took part in his first practice with Dallas (7-9) on Friday after signing earlier in the week. The 38-year-old has not played since Game 5 of the NBA finals for Oklahoma City.
