Capela was the 25th overall pick in the first round in this year's NBA draft. The Rockets considered keeping the Switzerland native in Europe for another season with hopes of using his salary-cap space to try to sign free agent forward Chris Bosh, who re-signed with the Miami Heat. Capela will be on the Rockets' roster next season, the source said.
The Rockets will pay the maximum $500,000 to Capela's previous club, France Chalon, to receive his official FIBA letter of clearance. Capela averaged 9.4 points and 7.4 rebounds for Chalon last season, but was not able to play for the Rockets' summer-league team because of his contract issue.
Under the NBA rookie scale, Capela will make $991,000 next season and $1.03 million the 2014-15 season with options for two more seasons.
