The Timberwolves will be without forward Al Jefferson indefinitely because of an injured Achilles' tendon.

Minnesota is already without forward Kevin Love for six to eight weeks because of a broken bone in his hand.

Jefferson didn't practice on Monday because of a sore Achilles after the injury limited him to just six minutes against the Bucks on Saturday night.

"It all depends on ... the treatments and the medication and whatever they're doing for him," coach Kurt Rambis said of Jefferson. "It all depends how quickly it affects it."
