The Jets have ruled out Kroft (back) for Sunday's game against the Falcons in London, Rich Cimini of ESPN.com reports.
Kroft was among three Jets that won't make the trip across the pond. With a back injury in tow and no practice so far this week, he'll be sidelined for the first time this season. In Kroft's stead, Ryan Griffin should be New York's primary tight end Sunday, while Trevon Wesco and Daniel Brown are candidates for elevated roles.
