Coby Karl waived by father's team
Both players were signed on April 11 but didn't appear in any games in the regular season or playoffs.
Karl averaged 14 points, 6.3 rebounds and 3.3 assists in four games with Denver's summer league team in Las Vegas. Butch appeared in two summer-league games, averaging seven points and six boards.
George Karl is on vacation as he prepares for his courtside return next month after fighting throat cancer since the spring.
