Minnesota Timberwolves point guard Ricky Rubio is a late scratch against the Phoenix Suns because of back spasms. Rubio worked out before the game on Saturday but was not able to play. The Timberwolves have three days off coming up before their next game, so Rubio likely will be ready to go by then. It was a disappointing setback for Rubio, who recently was allowed to play more minutes in his recovery from a torn anterior cruciate ligament. He is averaging 4.2 points and 4.0 assists since his return.
