Four added to roster

The Lakers signed four players to fill out their training camp roster. They inked guards Trey Johnson and Anthony Roberson and centers Andrew Naymick and Russell Hicks, none of whom are expected to make the roster for the start of the regular season. Training camp starts Sunday morning. There are 18 names on the roster, although there are only 17 healthy bodies since Andrew Bynum is sidelined after having offseason knee surgery.
