MINNEAPOLIS -- Minnesota Timberwolves point guard Ricky Rubio will not travel with the team for a two-game road trip to Utah and Denver this week because of back spasms.

Rubio missed the game against Phoenix on Saturday after being unable to get his back loosened up. Coach Rick Adelman says the team is just being cautious with Rubio, who is coming back from a torn ACL in his left knee. Rubio has played in five games this season after making his debut in the middle of last month.

Adelman thinks some of Rubio's back issues could be caused by him overcompensating for a knee that has not yet gotten back to full strength.

Rubio hopes to be ready to play at home on Saturday against Portland.
