Rockets center Clint Capela will become a restricted free agent next off-season, a person with knowledge of the Rockets' plans said.

The team and its starting center will let the today's deadline to reach an agreement on a contract extension pass.

Capela, 23,will begin his fourth season on Tuesday against the Warriors, but the Rockets have never signed one of their draft picks to a long-term extension while in their rookie contract. They will have the right to match any offer sheet he signs as a free agent in an off-season expected to be loaded with top talent and relatively little cap room.
