Source: Rookie guard C.J. McCollum could make Blazers debut Tuesday

Portland Trail Blazers rookie guard C.J. McCollum is expected to make his NBA debut on Tuesday against the Sacramento Kings if his NBA Development League stint over the weekend goes well, a source told Yahoo Sports.

McCollum has yet to play this season due to a left foot fracture he suffered during a Blazers practice in October. The 10th overall pick in the 2013 NBA draft, McCollum was assigned to the Blazers' D-League affiliate Idaho Stampede on Wednesday. McCollum will be activated prior to Portland's game in Sacramento on Tuesday if he plays well and has no physical setbacks in D-League games against the Rio Grande Vipers in Boise on Friday and Saturday, the source said.

"I'm just looking to get back into a rhythm and finish out the last requirement of my rehab phase," McCollum told Yahoo Sports.

McCollum averaged 23.9 points, 5 rebounds and 2.9 assists in 12 games as a junior for Lehigh University during the 2012-13 season before suffering a left foot fracture that ended his season. The Blazers plan to play the 6-foot-4, 200-pounder about 18 minutes in both games at shooting guard for Boise this weekend to simulate the minutes he could eventually play with Portland. The Blazers will have a basketball and medical representative in attendance to watch McCollum.

McCollum's time in Boise will be his first action since playing for the Blazers' summer league team. Even if McCollum is activated, the source said he would have to overcome the challenge of working his way into the rotation to get minutes. The Blazers' current first guard off the bench is veteran Maurice Williams.
