The official injury report has been released and both the Vikings and Bears may have to attack Sunday night's NFC North showdown at Soldier Field without key pieces of their defenses.

Vikings cornerback Antoine Winfield missed practice again today with stiffness in his neck and hasn't practiced since Sept. 30, two days before the team lost in Kansas City. Winfield is officially listed as doubtful by the Vikings for Sunday, a tag unlikely to change by kickoff.

Vikings receiver Percy Harvin, meanwhile, returned to practice today as a limited participant after being held out Thursday with sore ribs.

In Chicago, defensive end Julius Peppers has not practiced all week, dealing with a sprained medial collateral ligament in his left knee. Peppers is listed as doubtful for Sunday.
