"Pistons guard Brandon Knight stayed longer after practice Tuesday, getting acclimated to his new friend:

A plastic mask.

"It's my first time shooting with it," said Knight, who didn't go through any contact drills.

After going through shooting drills with assistant Ryan Hoover, Knight emphatically threw it down and cracked a joke before talking to reporters.

Knight was fitted for the mask Monday, and it looks similar to the ones worn by Richard Hamilton and Charlie Villanueva."
