Dallas Mavericks guard Seth Curry, the younger brother of NBA champion Golden State Warriors star Stephen Curry, will be sidelined indefinitely with a left leg injury, the Mavericks announced Saturday. The expected Mavericks backcourt starter has suffered a left tibia stress reaction and will be re-evaluated in a week, the club holding out hope he can be ready when the new season opens in just under two weeks. Curry, 27, is the son of former NBA sharpshooter Dell Curry.
