There’s been a curious sight at the last two Trail Blazers practices: CJ McCollum has been roaming the practice facility in Tualatin wearing two Nikes and no walking boot. And if all goes well, that boot soon will be gone for good. McCollum, who is recovering from a fracture to the fifth metatarsal bone in his left foot, said he’s optimistic he will gain clearance to ditch the walking boot “in a couple days.” Then, if all goes well next week during a medical checkup, he should be able to advance his rehabilitation work and inch one step closer to returning to the court. “The foot’s feeling pretty good,” McCollum said. “I’m just continuing to progress. It’ll be a good sign if I have a clean X-ray.” McCollum said he will have his foot X-rayed and examined on “Tuesday or Wednesday” of next week, which will be his first checkup since undergoing a non-operative ultrasound procedure Oct. 16 in Charlotte, N.C. And although his rookie season has momentarily been put on pause, the No. 10 selection of the 2013 NBA draft has been involved in heavy training to stay in shape. His rehabilitation includes work in the pool, on the stationary bike and in the weight room, where he goes through a series of dynamic lifting exercises, including lunges and squats designed to “build stability.” “It starts from the feet and goes all the way up to the core and back,” McCollum said. “The lifts are pretty intense and upbeat, so you’re breaking a good sweat in there. Working hard. But you can only do so much without running up and down the court. I’m just trying to take advantage of all the other opportunities.” Assuming he gets clearance to ditch the boot permanently, McCollum said his next opportunity will come this weekend, when he is allowed to start working out on the elliptical machine.
