The 76ers unveiled the start date and location of their training camp Friday. They also added four names to their preseason roster.

The team signed free agents Dan Gadzuric, Devin Searcy, Xavier Silas and Damien Wilkins to bring their training-camp roster to 17.

Camp, by the way, opens Tuesday at Saint Joseph’s University’s Hagan Arena and runs through Saturday, Oct. 6. The Sixers begin their slate of seven preseason games Oct. 11 at Orlando.

Gadzuric, a 6-11 forward who has played parts of 10 NBA seasons, was with the Knicks for two games last season. Searcy, an undrafted 6-10 forward who played in Japan last year, got time in five Orlando Summer League games for the Sixers.

Silas (pictured), a 6-5 guard, was a 2011 training-camp invitee who spent the bulk of his year with the Sixers’ D-League affiliate in Maine before signing with the team in April for their playoff run. Wilkins, a 6-6 guard who’s been in the league for eight seasons, played in 60 games last season with the Pistons.
