Wembanyama (ribs) is listed as doubtful for Wednesday's game against Portland, Shams Charania of ESPN reports.
Wembanyama suffered a left rib contusion during Monday's 115-102 win over the 76ers. It appears the 22-year-old will miss Wednesday's meeting with the Trail Blazers, though Chris Haynes of NBA TV reported Tuesday that his MRI came back clean, and he is considered day-to-day. If Wembanyama is indeed ruled out Wednesday, Luke Kornet is the favorite to enter the starting lineup.
