Patterson's agent, Odell McCants, said the deal is a standard rookie contract, with the first two years guaranteed and two one-year options. McCants said Patterson planned to sign the contract after the Rockets' summer league game in Las Vegas on Tuesday night.
The Rockets chose the 6-foot-9, 236-pound forward from Kentucky with the 14th pick overall in the draft. Patterson scored 18 points in the Rockets' summer-league opener in Las Vegas on Friday.
The agreement was first reported by KRIV-TV.
