Vikings defensive tackle Kevin Williams missed today's practice to tend to a personal matter, but his knee is good to go on Sunday in Chicago, coach Leslie Frazier said after practice.

"[Missing practice] has nothing to do with him physically," Frazier said. "He should be ready to go on Sunday."

Williams, who suffered a severely strained right knee in the third preseason game, missed the season opener at Detroit. The Lions won 34-24 and were able to run well between the tackles with running back Reggie Bush, who averaged 4.3 yards on 21 carries.

Williams was listed as probable. The Vikings listed six other players as probable. The only one with limited participation in today's practice was center John Sullivan (knee). Listed as probable with full participation were: LB Larry Dean (shoulder), LB Erin Henderson (heel), RT Phil Loadholt (knee), S Mistral Raymond (shoulder) and CB Josh Robinson (quadriceps).

For the Bears, CB Charles Tillman (knee) and DE Julius Peppers (illness) were listed as probable. Peppers was limited in practice. Tillman had full participation.
