Green was originally signed to the Patriots as a rookie free agent in 2013 and played in two games last season, accruing no statistics.
A scout who has studied Green told Rapoport that Green is a "solid backend type of guy who definitely brings value on special teams. Really good practice squad type of player who can be moved up and be activated if injury occurs. ... But you don't want him out there for a prolonged period of time in coverage, likely would get exposed."
It may be a rough four-game stretch for Dallas sans Scandrick, and they hope the second-year player from Illinois can mitigate the damage.
