The Eagles placed Jorrick Calvin on injured reserve today because of an unspecified back injury. The team has not yet added another player to their 53-man roster to replace the cornerback/returner.
Calvin injured his back against the Giants and didn't practice yesterday or today. Calvin had primarily handled kick returns for most of the season and also filled in occassionally in returning punts.
The Eagles acquired Calvin in a trade with the Arizona Cardinals just before the start of the season.
The Eagles reportedly worked out a few kick return specialists this week. Receivers Chad Hall and Jeremy Maclin have returned kicks before.
