Superstar receiver Calvin Johnson is listed as doubtful on the Detroit Lions' official injury report for Sunday's game at Minnesota.
Johnson didn't practice all week because of an ankle injury that has hampered him the last couple weeks.
Running back Reggie Bush also didn't practice all week because of an ankle injury, but he's listed as questionable.
Backup running backs Joique Bell (concussion) and Theo Riddick (hamstring) are probable after missing last Sunday's game. Cornerback Cassius Vaughn also is expected to return after missing the last three games with an ankle injury.
While Detroit could be shorthanded offensively, the same is true for Minnesota's defense. Linebacker Chad Greenway (hand/rib) is doubtful and safety Harrison Smith (ankle) is questionable.
Quarterback Teddy Bridgewater (ankle) is listed as probable after missing the Vikings' game last week, but tight end Kyle Rudolph (abdomen/groin) has been ruled out.
