The San Antonio Spurs face a potential double blow to their lineup ahead of a crucial Friday night showdown with the Dallas Mavericks. The team's latest injury report lists both franchise cornerstone Victor Wembanyama and rookie standout Stephon Castle as questionable, casting a shadow over the home matchup.

Wembanyama, the reigning Rookie of the Year, is nursing a left rib contusion suffered earlier in the week. His absence would be a significant hurdle for the Spurs' offense and defense, potentially forcing Luke Kornet into the starting lineup with increased minutes for Mason Plumlee and Kelly Olynyk. Adding to the drama, Wemby needs to log at least 20 minutes in one of San Antonio's final two games to remain eligible for regular season awards, making his status a major storyline.

Meanwhile, fellow top prospect Stephon Castle is also in danger of missing his second straight game due to left foot soreness. His potential absence would test the Spurs' backcourt depth, likely opening the door for more significant contributions from Dylan Harper and Carter Bryant.

This injury news arrives as the 61-19 Spurs look to maintain momentum against a struggling Mavericks squad. While San Antonio aims to secure another home victory, the possible sidelining of their two most exciting young talents could dramatically alter the game's dynamics and force other players to step up in a high-stakes Western Conference clash.
