Vikings injury report: DBs still out

LONDON -- Aside from Christian Ponder being limited in practice for the Vikings on Wednesday, the team was still without its three defensive backs -- Chris Cook, Jamarca Sanford and A.J. Jefferson -- who were injured during last Sunday's loss to the Cleveland Browns.

All three players did not practice on Wednesday, and it remains to be seen how many of them will be available on Sunday against the Pittsburgh Steelers at Wembley Stadium. If the Vikings' depth is limited, coach Leslie Frazier said he would likely stick with the same arrangement the Vikings used last Sunday, playing Marcus Sherels and Josh Robinson in the base defense and using rookie Xavier Rhodes as the left cornerback in the team's nickel package. But Frazier, again, admitted the Vikings' cornerback depth is a concern.

Whether Antoine Winfield could be a solution to that problem remains to be seen. General manager Rick Spielman would not address whether the Vikings have had any conversations with Winfield about coming out of retirement, adding, "I can't rule anything out. You never know."

Here is the rest of the Vikings' injury report:

  • Tight end Rhett Ellison, who missed last Sunday's game with a hyperextended knee, also sat out of practice.

  • Ponder was limited in practice because of a rib injury, with Matt Cassel taking some of his reps in practice.

  • Running back Matt Asiata (hamstring) and defensive tackle Kevin Williams (knee) were also limited.

  • Linebacker Erin Henderson (heel) and long-snapper Cullen Loeffler (neck) practiced in full.
