The Philadelphia Eagles fell short against the Dallas Cowboys on Christmas Eve in what was one of the best games of the week. The NFC East rivals played right to the wire with the Cowboys coming out ahead, 40-34.

The loss put off the Eagles from clinching the division and No. 1 seed in the NFC for at least one more week. Their next victory would clinch both as they are still two games clear of the Cowboys in the NFC East and one ahead of the Minnesota Vikings for the No. 1 seed, but they own the tiebreaker over Minnesota from their Week 2 head-to-head victory.

While the loss to the Cowboys record-wise wasn’t very damaging, the Eagles did suffer some big losses on the roster from injuries. Pro Bowl right tackle Lane Johnson will be sidelined for the remainder of the regular season with an abdominal tear and he will be joined by cornerback Avonte Maddox.

Maddox suffered a significant toe injury against the Cowboys last weekend and will be sidelined indefinitely. He is going to undergo an MRI to determine the exact diagnosis, but he is going to certainly miss some time.

It is a big blow for an Eagles secondary that has already been playing without C.J. Chauncey-Gardner, who suffered a lacerated kidney in Week 12 against the Green Bay Packers. Maddox has played in nine games this season, starting eight of them, playing a lot of his snaps in the slot.

On the season Maddox has 43 combined tackles, three tackles for loss, two quarterback hits and one sack. He has also recorded one interception and three passes defended, three forced fumbles and one fumble recovery as he has been a key cog in the secondary’s strong performance this season.

Without Maddox in the lineup, Josiah Scott, Andre Chachere and Zech McPherson could see some more snaps defensively. The Eagles’ secondary has been a strength throughout the season but they have been weakened in recent weeks up the middle because of injuries.
