The Giants will be without Tyrone Tracy for at least the next four games because of a hamstring injury and they’ll pluck a player from another team to fill the opening on their active roster.

General Manager Joe Schoen announced that the Giants will sign running back Gregory Desrosiers off of the Chargers’ practice squad.

Desrosiers signed with the Chargers after going undrafted this year. He played at Louisville, UMass and Memphis over the last six seasons.

Cam Skattebo and Devin Singletary will be the top backs on the Giants’ depth chart with Tracy out of action. Phil Mafah and Grant Finley are on their practice squad.
