According to the San Antonio Express News (via probasketballtalk.nbcsports.com) the San Antonio Spurs are to workout forward Darius Miles.
Miles has dealt with numerous microfracture knee surgeries since coming to the NBA. He has had stints with the Los Angeles Clippers, Portland Trail Blazers, Cleveland Cavaliers, Boston Celtics and the Memphis Grizzlies. He last played in the NBA in the 2008-2009 season with the Grizzlies.
He is not a typical "Spurs player" in the sense of handling himself well on and off the court. He was suspended by the NBA for violating the league's substance abuse policy and had confrontations with former Blazers' coach Maurice Cheeks.
For his career he has averaged 10.1 points, 1.9 assists, 4.9 rebounds and shot 47% from the field.
