Denver Nuggets waive coach's son, Coby Karl, and Brian Butch

DENVER – The Denver Nuggets have waived guard Coby Karl, the son of coach George Karl, along with center Brian Butch.

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 to return to courtside next month after fighting throat cancer since the spring.
