TORONTO - The remodelling of the Toronto Raptors continues.

Toronto acquired forward Amir Johnson and guard-forward Sonny Weems from the Milwaukee Bucks on Tuesday for guards Carlos Delfino and Roko Ukic.

The Raptors facilitated a sign and trade with Delfino, who spent last season in Russia.

"Carlos made it clear he would prefer to play elsewhere if he were to return to the NBA," Raptors president Bryan Colangelo said in a statement. "There were limited sign and trade scenarios available, but acquiring Amir Johnson in this deal gives us another long, talented young big man whose best basketball is ahead of him."

Johnson spent the past four seasons in Detroit before getting dealt to Milwaukee in June. He appeared in 62 games for the Pistons last year and led the team in field goal percentage at .595.

The 22-year-old averaged 3.5 points, 3.7 rebounds and 0.97 blocks per game.

Weems appeared in 14 games as a rookie with the Denver Nuggets last year.

Delfino spent last season in Russia after seeing action in 82 games with the Raptors in the 2007-08 campaign. He averaged 9.0 points and 4.4 rebounds for Toronto.

Ukic made his NBA debut last season following six seasons overseas. He averaged 4.2 points, 2.1 assists and 12.4 minutes in 72 games.
