The team made the move in order to fit linebacker Jon Bostic onto the roster. Bostic, a third-year pro, was acquired in a trade with Chicago Monday.
Cadet suffered a hamstring strain during practice on Aug. 8 and missed virtually the entire month. Still, he made the initial 53-man roster, but was inactive in two of the Patriots' first three games.
He signed a two-year deal this past offseason after spending three years with the New Orleans Saints.
We just posted a news story Monday from a beat writer who said not to count out Cadet for a potential bigger, future role with the team. The Pats could still bring him back if he doesn't find work, but for now this is great news for Dion Lewis owners. James White is still a similar back on the NE roster but Lewis looks like he'll keep his role for a while.
