MINNEAPOLIS — David Kahn is heading back to Spain as the Minnesota Timberwolves continue to wait to see if point guard Ricky Rubio will commit to playing in the NBA next season.

Kahn and assistant GM Tony Ronzone departed on Wednesday to scout the Euroleague Final Four. Rubio is not playing in the tournament, but is playing in the Spanish League.

Rubio has to exercise a $1 million buyout with Regal Barcelona and sign his current rookie deal by May 31 if he wants to avoid risk losing money with a new NBA collective bargaining agreement. The Timberwolves can contribute $500,000 toward that buyout.

Kahn and Ronzone also will be there to visit former draft picks Henk Norel, Nemanja Bjelica and Paolao Prestes.
