Warriors reserve forward Marreese Speights has a strained right calf that could keep him out for the rest of Golden State's series with the Memphis Grizzlies. The Warriors said Sunday that Speights had an MRI exam that showed a moderate strain, and the forward will be re-evaluated in one week. Speights was hurt in the fourth quarter Saturday night of a 99-89 loss to Memphis, and he hopped off the court to the locker room.
