When the Buffalo Bills open training camp Thursday, veteran running back Frank Gore might not be physically ready to be on the practice field.
The 36-year-old Gore, one of the 18 free agents the Bills signed in the offseason, has been placed on the non-football injury list, according to the NFL's official transaction report. The nature of the injury was not disclosed.
Gore is considered day-to-day with a minor issue he sustained while working out, an NFL source told The Buffalo News Monday. The source also said that Gore was expected to miss little, if any, time.
The Bills also placed tight end Tyler Kroft, another free-agent signee who suffered a broken foot at the start of organized team activities that required surgery, and offensive lineman Jeremiah Sirles, who was seen limping off the field during an OTA workout, on the physically unable to perform list.
Gore is part of a crowded backfield that includes incumbent LeSean McCoy and fellow newcomers T.J. Yeldon, another free-agent signee, and third-round draft pick Devin Singletary. For his career, Gore has 18,544 yards from scrimmage and 95 total touchdowns.
The Bills also signed former Miami Dolphins offensive guard Isaac Asiata, according to a tweet from his agent, David Canter of DEC Management.
Asiata, 6-foot-3, 345 pounds, joined the Dolphins as a fifth-round draft pick from Utah in 2017. He was waived by Miami on Sept. 1, 2018, and assigned to its practice squad, then was promoted to the active roster in November. He was waived/injured in May and then released on June 6.
