Free agent forward Joe Johnson is in Detroit today to work out for the Pistons, sources tell Dave McMenamin of ESPN (Twitter link).

Johnson’s workout with the Pistons had been expected, as a report last week indicated that the NBA veteran, who has already worked out for the Sixers, would also audition for the Pistons, Bucks and Nets. However, Frank Isola of The Athletic provides some new info, suggesting during an appearance on SiriusXM NBA Radio today that he has heard Detroit is the frontrunner to sign Johnson (Twitter link via Noah Coslov).

As Bobby Marks of ESPN observes (via Twitter), there’s a connection between Johnson and Detroit — the 38-year-old used to be represented by former agent Arn Tellem, who is now the Pistons’ vice chairman.
