The Rockets are signing Dexter Pittman and waiving Greg Smith.
Smith, a 6-10 forward/center, has been unable to come back from knee injury and has missed most of the season. He was not with the Rockets on their current road trip.
Pittman, a big body at 6-11 and 308 pounds, is signed for the rest of this season and also for next, but the second year is not guaranteed. He is eligible for the Rockets playoff roster and could provide some big-man minutes behind Dwight Howard and Omer Asik.
