Dallas Mavericks sixth man J.J. Barea suffered a torn right Achilles tendon during Friday's 119-115 road victory over the Minnesota Timberwolves, the team announced Saturday.
The Mavs said Barea is weighing his options for surgery.
Barea, 34, a longtime Dallas fan favorite who played a key role on the 2011 championship team, has been the leader of one of the NBA's most effective bench units this season. He is averaging 10.9 points and 5.6 assists in 19.8 minutes per game.
The injury ends Barea's season and puts in doubt his availability for the start of next season.
