The Timberwolves used a provision in the NBA's new labor deal to waive guard Fred Hoiberg on Monday, a team spokesman said, less than two months after he underwent surgery to correct an enlarged aortic root.

Hoiberg's NBA career may be in jeopardy. He had a pacemaker implanted after his surgery on his aorta, which was performed June 28 at the Mayo Clinic in Rochester, Minn.

Officials around the league say they believe Hoiberg would become the first player in the NBA to play with a pacemaker, a small electrical device designed to keep the heart beating properly.

Hoiberg, who will turn 33 in October, is a veteran of 10 NBA seasons, the last two with the Wolves. He became well known for his professionalism and three-point shooting accuracy.

He averaged 6.7 points in 2003-04 and 5.8 last season. He led the NBA in three-point accuracy last season, when he made 48.3 percent.

The deadline for NBA teams to waive players under the amnesty provision is midnight Monday. The provision allows teams to save a dollar-for-dollar penalty against the luxury tax. Teams must pay the players' full salary, and it still counts against the salary cap.
