Marc Stein at ESPN.com: The NBA informed all 30 teams last week that the arbitrator who will rule on the grievance filed by Jamaal Tinsley against the Indiana Pacers has denied a motion by the Pacers to dismiss the grievance. The grievance was filed on Tinsley's behalf in February by the NBA Players Association, challenging the Pacers' decision to bar Tinsley from participating in any team activities before last season began while they tried to trade him. Indiana's motion to dismiss in May was made on the grounds that the grievance was not filed in a timely fashion. Arbitrator Calvin Sharpe ruled in favor of Tinsley, concluding that the issue of timeliness would be weighed along with all other aspects of the dispute when the sides convene for a hearing on the matter scheduled for July 27-29. According to a Wednesday report from David Aldridge of TNT and NBA.com, Tinsley "has been working out in the Atlanta area and is in terrific condition, considering how long he's been out of action."
