Vince Ellis of the Detroit Free Press reports:

In what team sources termed some type of player protest, Tracy McGrady, Tayshaun Prince, Richard Hamilton and Chris Wilcox were missing from this morning’s shootaround before tonight’s game against the Philadelphia 76ers.

Team spokesman Cletus Lewis said Rodney Stuckey and Austin Daye missed the team bus as well, but they did arrive toward the end of the media session.

Lewis said McGrady had a headache, Prince had an upset stomach and Hamilton and Wilcox missed the bus from the team hotel.

Ben Wallace also missed the shootaround. Lewis said Wallace was dealing with a family matter. Wallace has missed games and practices over the past month because of the issue.

Only Greg Monroe, Will Bynum, Ben Gordon, Charlie Villanueva, Jason Maxiell and DaJuan Summers were full participants in the morning shootaround.

Sources indicated that the discontent is directed at Pistons coach John Kuester, who has clashed with players repeatedly this season. The organization downplayed the absences, insisting Prince and McGrady were ill.
