Buffalo Bills tight end Tyler Kroft broke a foot on Monday during the opening of the team's organized activities and will need surgery.
Coach Sean McDermott made the announcement on Tuesday, adding that there is no timetable for the return of Kroft.
It's the same foot that Kroft broke last season when he was Cincinnati Bengals, an injury that knocked him out of 11 games.
Meanwhile, wide receiver Cole Beasley and center Mitch Morse, two other signatures of free agents of the Bills this offseason, also do not participate in the OTA. McDermott said both players underwent central muscle surgeries a few weeks ago and are not authorized to participate.
Kroft was expected to be the tight end of the Bills after signing a three-year contract and $ 18.75 million with the team in free agency. Received $ 8.3 million guaranteed.
He started with 35 games in total for the Bengals, who selected him in the third round (35 total) of the 2015 draft, catching 67 passes for 661 yards and eight touchdowns.
