The Portland Trail Blazers announced Thursday that rookie guard CJ McCollum has been cleared for three-on-three action as he recovers from a broken bone in his left foot. He is still without a timetable to return to the court.

McCollum discussed the injury, which occurred during training camp, right here. He underwent an ultrasound procedure to treat the injury in mid-October and has been listed as out indefinitely since. McCollum underwent a follow-up in mid-November and a CT scan this week.

McCollum previously broke the fifth metatarsal in his left foot back in January, and he underwent surgery after sustaining that injury. His initial recovery timeline after that injury was set at 8-to-10 weeks but he did not return for the rest of the 2012-13 NCAA season. McCollum did not participate in the skills portion of the Chicago pre-draft combine in May but he went through a solo workout with the Blazers in June. He told reporters that he was fully healed prior to playing for the Blazers at the 2013 Las Vegas Summer League in July.

McCollum, 22, was taken with the No. 10 pick in the 2013 NBA Draft. He averaged 21 points, 4 rebounds and 3.4 assists in 34.6 minutes over five Summer League appearances.

McCollum -- who penciled as the fourth guard on the Blazers' depth chart behind Damian Lillard, Wesley Matthews and Mo Williams -- was interviewed earlier this season on Blazers Courtside. He was regarded by his peers as one of the favorites to win the 2014 Rookie of the Year award prior to his injury.
