Christian Ponder, Minnesota Vikings (hip - questionable)
MIN (2-10) @ DET (7-5), 1pm
The Vikings' rookie QB played well overall in his team's loss to Denver last week, but suffered a hip injury during the game and was spotted limping on the sidelines. As a result, he has missed most of the week's practices and backup Joe Webb has taken the majority of the snaps with the first team. At this point, it appears unlikely that Ponder would get the start on Sunday against Detroit, although neither he nor Webb are likely to factor in your fantasy plans either way.
Adrian Peterson, Minnesota Vikings (ankle - questionable)
MIN (2-10) @ DET (7-5), 1pm
Peterson missed the Vikings' Week 13 loss to Denver due to a high ankle sprain and has been limited in practice all week. Peterson himself has stated he wants to play and claims he's at about 80% health after taking last week off. Although Detroit's defense has been stout most of the year, Peterson has historically done well against the Lions, and it would be tough to sit him on your fantasy roster if he is able to play. If not, Toby Gerhart would once again get the start at running back for the Vikings.
Kevin Smith, Detroit Lions (ankle - questionable)
DET (7-5) vs. MIN (2-10), 1pm
Smith, who left last week's loss to New Orleans after aggravating an ankle injury, has been limited in practice this week. Reports out of practice on Friday were that Smith was having difficulty cutting on running plays, and if Smith suits up on Sunday don't be surprised if Maurice Morris gets the bulk of the carries.
Miles Austin, Dallas Cowboys (hamstring - questionable)
DAL (7-5) vs. NYG (6-6), 8:20pm
Austin has missed most of the season thus far due to a nagging hamstring injury that has been an issue since the preseason, but despite being limited in practice this week it appears he will get the nod on Sunday night against the Giants. Given the emergence of Laurent Robinson at WR (himself questionable due to a shoulder injury) and the frequency with which hamstring strains tend to recur, Austin fantasy owners may want to tread lightly this week.
Von Miller, Denver Broncos (thumb - questionable)
DEN (7-5) vs. CHI (7-5), 1pm
Miller, who missed last week's win over Minnesota after tearing ligaments in his right thumb the prior week, has been wearing a cast this week in his limited action in practice. It appears he will play on Sunday against the Bears, but his time may be limited to pass-rushing situations.
Patrick Willis, San Francisco 49ers (hamstring - questionable)
SF (10-2) @ ARI (5-7), 4:05pm
Willis suffered a right hamstring injury in the first quarter of the 49ers' Week 13 win over the Rams and has missed practice the entire week. Although he is officially listed as questionable on the team's injury list, his not having practiced - along with the fact that the team has already clinched the NFC West - makes it seem unlikely that he will suit up on Sunday at Arizona. LB Larry Grant is likely to get the start in Willis' place.
