The Eagles were bitten by the injury bug hard on Sunday, which will likely lead to more than just Jon Dorenbos landing on IR.

One of the replacement players on the roster will be cornerback Dwayne Gratz. The Eagles are planning to sign Gratz, according to a league source. The Philadelphia Inquirer's Jeff McLane first reported the move.

Gratz, 26, is a former third-round pick of the Jacksonville Jaguars, but most recently played for the Rams. Gratz was taken 64th overall in 2013 and had been with the Jags until they cut him in October. He was claimed by the Rams and spent a little over a month in L.A.

One of the three injured players that could be headed to IR that head coach Doug Pederson listed on Monday was safety Jaylen Watkins. With Watkins out, it likely means Malcolm Jenkins won't be able to play in the slot as much anymore. Gratz will provide the Eagles with some depth in the secondary.

The Piscataway, N.J. native — who attended Piscataway HS, same as Jenkins — has three interceptions (one returned for a touchdown) and 13 passes defensed in his NFL career. He's played in 43 NFL games and has started 25.
