Coughlin (pectoral) reverted to the Giants' practice squad and was placed on the team's practice-squad injured list Monday, Dan Salomone of the Giants' official site reports.
Coughlin made the Giants' initial 53-man roster, but it appears he's reverted to the team's practice squad after sustaining a pectoral injury Sunday. The Minnesota product has also been added to New York's practice squad IR, meaning he'll be forced to miss at least the team's next four games. Expect Ty Summers to see more work as a rotational linebacker and on special teams while Coughlin remains sidelined.
