EDEN PRAIRIE, Minn. -- While the Vikings are waiting to see whether running backs Adrian Peterson and Toby Gerhart are able to play Sunday, they'll have to figure out how to handle one of the league's hottest offenses with a secondary that is looking increasingly thin.
Cornerback Xavier Rhodes is doubtful for Sunday's game against the Philadelphia Eagles with a sprained ankle, coach Leslie Frazier said Friday, and cornerback Chris Cook showed up on the Vikings' injury report for the first time Friday with a knee injury that limited him in practice. The oft-injured cornerback is listed as questionable, and if both he and Rhodes were to miss the game, it would leave the Vikings without their top three cornerbacks Sunday.
Frazier said he would likely start Marcus Sherels in place of Rhodes, but he would have to figure out another plan if Cook were unable to go. The Vikings have been using safety Robert Blanton at cornerback, and he would likely play there Sunday. Shaun Prater is also healthy, and the Vikings have cornerbacks Kip Edwards and Robert Steeples on their practice squad. They also worked out several cornerbacks this week, Frazier said.
"When we’re getting as thin as we are, everybody is a candidate to be moved around," Frazier said. "So you don’t rule out any possibilities at this point."
The Vikings have the league's second-worst defense this season as it is, and with so many players missing in the secondary, they could be easy prey for Eagles quarterback Nick Foles on Sunday.
In other Vikings injury news:
Gerhart did some work in practice Friday, though Frazier said the Vikings didn't test his quickness as much as his overall stride. They will continue to evaluate him Saturday and possibly Sunday. "To get out there and move around, I felt pretty good," Gerhart said. "We'll take it day-to-day, keep getting treatment, keep evaluating and see what happens."
Cornerback Josh Robinson (fractured sternum) is still out.
Guard Brandon Fusco (knee) did not practice Friday and is doubtful for Sunday's game, though Frazier said Fusco "has a chance" to play. The Vikings had guard Jeff Baca -- who has been inactive for all but one game this season -- working in Joe Berger's special-teams spot Friday, indicating they would likely put Berger at Fusco's right guard spot.
Linebackers Larry Dean (knee) and Chad Greenway (wrist) are probable for Sunday's game. Greenway, who has been playing with a broken wrist all season, said he has been able to function better now that he's playing with a pad on both sides of his wrist, rather than a full cast, and sounded optimistic Friday that he wouldn't need surgery to set the bone after the season.
