The Bills placed Kroft (foot) on their PUP list Monday, Sal Capaccio of WGR Sports Radio 550 Buffalo reports.
Kroft is nursing a broken right foot sustained during OTAs in May. His designation is no surprise, given that the 2015 third-round pick was initially given a recovery estimate of 3-4 months, and his status for Week 1 remains up in the air. As long as Kroft remains sidelined, more reps will be made available for rookie tight ends Dawson Knox and Tommy Sweeney.
