PHILADELPHIA (CBS) – The Eagles have signed wide receiver Mardy Gilyard, and released safety Jaiquawn Jarrett, the team announced.

This most likely means that receiver Jeremy Maclin will not be available on Sunday, or will be limited. Reid announced that Maclin suffered a hip pointer in Sunday’s win at Cleveland. It’s also likely that safety Colt Anderson, who is already on the 53-man roster, will be active for Sunday’s game against Baltimore. The Eagles now have Nate Allen, Kurt Coleman, David Sims and Anderson at safety.

Gilyard, who is in his third NFL season, was with the Eagles during the preseason, and was cut when the team needed to get down to 53 players. Maclin’s injury left the Eagles short at wide receiver. Gilyard was a fourth round pick by the St. Louis Rams in the 2010 draft.

Jarrett’s play has been disappointing since the Eagles took him in the second round of the 2011 draft. With a full offseason under his belt, the Eagles expected more from him this year. His play was mediocre at best during the preseason, and did not play well on Sunday against the Browns.

The team also added tight end Derek Carrier to the practice squad, and released tight end Chase Ford from the practice squad.

Carrier originally signed with the Oakland Raiders as a rookie free agent following the 2012 draft after playing collegiately at Beloit College in Wisconsin.
