The Houston Chronicle (Jonathan Feigen) reports: The Rockets agreed to release center Loren Woods from his contract on Monday, then signed this season’s first-round pick Donte’ Greene before their first game in the Las Vegas NBA Summer League on Monday. Woods, who had been signed late last season to a partially-guaranteed contract for next season, had been receiving interest from several European teams and asked for his release. The Rockets had been considering him as a potential backup for Yao Ming, particularly if they are unable to sign free agent Dikembe Mutombo.
