Ray McCallum: Contract with Charlotte expires

McCallum's second 10-day contract with the Hornets expired Friday, MLive.com's Aaron McMann reports.

The Hornets haven't formally announced whether they'll release McCallum or sign him to a contract for the rest of the season, but it appears they will go with the former route, as the team formally signed Johnny O'Bryant to a 10-day deal Friday, filling their 15th roster spot. McCallum never ended up seeing the floor during his two 10-day stints with the Hornets, as coach Steve Clifford opted to use Kemba Walker and Brian Roberts as his sole point guards. Look for McCallum to report back to the D-League's Grand Rapids Drive.
