Adrian Peterson is listed as questionable for Sunday's game at Green Bay because of a groin injury.

Peterson did some work in Friday's practice after missing two days of practice.

Middle linebacker Erin Henderson was declared out while he tends to a personal matter. Coach Leslie Frazier said Henderson probably won't make the trip and he declined to give any more specifics about Henderson's absence.

"Not at this point," Frazier said. "But at some point I probably will be able to. But not at this point."

Henderson is the team's leading tackler. Audie Cole will start in his place.

Defensive end Brian Robison is listed as questionable because of a muscle spasm in his neck that he suffered in Thursday's practice. Robison was unable to practice Friday.

Wide receiver Greg Jennings (Achilles) also is listed as questionable but he told reporters Thursday that he definitely expects to play. Jennings was listed as probable against Seattle last week but he was made inactive on game day after experiencing a setback.

Center John Sullivan is listed as questionable, but he has cleared the NFL concussion protocol and is expected to play.
