If Harris returns to Dallas, it will mark his third stint with the franchise. The Mavericks acquired him in a draft night trade with the Wizards in 2004 and kept him until 2008, when they traded him to the Nets. Harris returned to Dallas as a free agent in 2013 and spent five more years with the Mavs before being shipped to Denver in February.
The 35-year-old combo guard appeared in 71 games last season, averaging 8.4 PPG. His addition will give the Mavericks 16 players under contract.
