CHICAGO - Swiss swingman Thabo Sefolosha and US teenage forward Tyrus Thomas, both first-round National Basketball Association Draft picks, signed on with the Chicago Bulls.

Thomas, selected fourth overall, will make 5.63 million dollars in the first two years of his deal under the NBA's rookie salary limits. Sefolosha, selected 13th, will earn 2.93 million dollars in the first two years.

The Bulls, who hold options for the next two years of each man's contract, swung transfer deals to obtain both players.

Thomas, 19, departed Louisiana State University after his freshman season and helped the Tigers reach the semi-finals of the US national college tournament, averaging 12.3 points, 9.2 rebounds and 3.1 blocked shots.

Sefolosha, 22, averaged 12.0 points and 6.4 rebounds in 21 games in his first season with Italy's Angelico Biella.

He also averaged 9.4 points, 7.0 rebounds and 1.5 blocks in 42 games with Chalon-Sur-Saone of the French league in the 2004-05 season.
