The Rockets have waived Jon Leuer and Jerome Jordan, according to Jonathan Feigen of the Houston Chronicle (via Twitter). When the two players clear waivers, the Rockets will have the necessary roster space to finalize their offer sheet for restricted free agent Omer Asik.
Both Leuer and Jordan were acquired by Houston in recent trades for salary-matching purposes. Leuer came from the Bucks in the June deal that sent Samuel Dalembert to Milwaukee, while Jordan arrived from New York in the Marcus Camby sign-and-trade.
I believe both players were on non-guaranteed contracts for 2012/13, so the Rockets shouldn't have to take a cap hit for releasing either one. The pair will become unrestricted free agents in 48 hours, assuming both of them clear waivers.
