The events surrounding the arrest and ensuing season-ending injury of Atlanta Hawks forward Thabo Sefolosha in New York on Wednesday have come under increasing scrutiny by the National Basketball Players Association and the Hawks during the past 24 hours, league sources say.

Sefolosha was injured in the early-morning hours Wednesday outside a Manhattan night club, where a police report states he was resisting arrest. Sefolosha and Hawks teammate Pero Antic were arrested on suspicion of interfering with the efforts of local police to set up a crime scene after the stabbing of Indiana Pacers forward Chris Copeland.

"The players' union is concerned about the circumstances of Thabo Sefolosha and Pero Antic's arrest and is doing its own investigation of the situation," NBPA spokeswoman Tara Greco said. "The union was fully engaged in supporting all three players in court and in the precinct this week, and will continue to stay engaged as each situation evolves."
