Sheppard was injured going for a tackle on a running play in the
fourth quarter of Sunday's 23-20 victory over the New York Giants.
He was replaced by Rod Hood.
Should the Eagles advance, it's possible Sheppard could return
to the lineup.
"It's a little tricky," coach Andy Reid said Monday. "This
week for sure he won't be back. We'll see down the road, if there
is a down the road."
Sheppard missed three games with an ankle injury in September,
but had six interceptions and earned his second trip to the Pro Bowl.
McNabb (knee) went down in Week 11 and Kearse (knee) has been
sidelined since Week 2.
