Portland Trail Blazers Ranger, CJ McCollum, Will be out for at least four weeks after additional tests revealed a small fracture in his left foot and a sprain in the middle of the foot, the team announced Monday night.

McCollum was knocked out in the first half of the Blazers’ 112-106 win over the Atlanta Hawks on Saturday with what the team described as a left-foot sprain. It was not clear when he was injured, but it seems so Clint Chapel Hawks stepped on McCollum after throwing the ball in the first quarter.

After that match, Blazers coach Terry Stuts said the X-rays ruled out a more serious injury.

Stuts told reporters Monday morning that McCollum’s sprained left foot would be re-evaluated within a week. But Blazers, in a statement late Monday night, said more images showed “a small fracture of the wedge-shaped lateral line” in McCollum’s left foot.

The team said McCollum would wear walking shoes and would be re-evaluated within four weeks. McCollum averages 26.7 points and 5.0 assists in 13 games this season.
