Duren needs two more weeks; Knueppel and Will Richard also sidelined

The Pistons will re-evaluate Jalen Duren's right hamstring strain in another two weeks, though he has been cleared for on-court basketball work. He has missed seven straight games since getting hurt Oct. 23 against Miami, and if the timeline holds his next checkpoint is Nov. 22 at Atlanta. Detroit went 4-2 without him before Sunday's loss to the Lakers. Elsewhere, Charlotte's Kon Knueppel is expected to miss four more weeks with a hamstring strain, and Golden State's Will Richard is out indefinitely with a torn UCL in his left thumb.
