Perk talks with media. It's his right knee. Expects to be back practicing tomorrow. Says he'll play Friday.

KG (ankle) and Perk (knee) both sat our today's practice. KG likely not practicing tomorrow, Perk could be back tomorrow.

Maintenance day for KG and Perk? They are not on court as practice opens to reporters. We'll find out more shortly from Doc.

They'll both play on Friday I believe, but we need them at as close to 100% as possible. KG is obviously key, but Perkins's defense is one of the most underrated elements on the Celtics. Though the stat can be misleading at times, there's a reason Perk often has the highest +/- on the team.
