The Cleveland Cavaliers have signed guard Kyrie Irving and forward Tristan Thompson, the No. 1 and No. 4 overall selections, respectively, in the 2011 NBA Draft.

Irving, 19, played in 11 games as a freshman for Duke last season, averaging 17.5 points, 3.4 rebounds and 4.3 assists in 27.5 minutes per game. He shot 52.9 percent, including 46.2 percent from three-point range over that span, but missed the majority of the season with a right toe injury.

Thompson earned Big 12 Freshman of the Year honors last season after averaging 13.1 points and team highs of 7.8 rebounds and 2.4 blocks in 30.9 minutes per game in 36 games with Texas.
