The San Antonio Spurs face a potential double blow as they prepare to host the Portland Trail Blazers on Wednesday night. The team's latest injury report lists both rookie sensation Stephon Castle and reigning Rookie of the Year Victor Wembanyama as doubtful, casting a shadow over this Western Conference clash.

Wembanyama, the Spurs' defensive anchor and offensive centerpiece, is sidelined with a left rib contusion suffered in Monday's win over Philadelphia. His absence is a significant hurdle for a Spurs team looking to solidify its standing. In his place, Luke Kornet is expected to step into the starting lineup, with Mason Plumlee and Kelly Olynyk seeing expanded minutes off the bench.

Compounding the challenge, fellow standout Stephon Castle is also listed as doubtful due to right knee soreness. This would mark his first missed game in over a month, disrupting the Spurs' backcourt chemistry. His potential absence opens the door for increased roles from Dylan Harper and Carter Bryant, who will need to step up against a hungry Trail Blazers squad.

Despite the injury concerns, the Spurs, boasting an impressive 60-19 record, will look to defend their home court. Tune in to ESPN at 9:30 p.m. ET to see how San Antonio adjusts its game plan on the fly in a crucial late-season test.
