NEW YORK — The NFL plans to talk to teams about how practices are conducted following a 73 percent increase in concussions during preseason workouts in 2017.

Executive vice president Jeff Miller said Friday that data from the league’s annual preliminary report on injuries will be discussed with coaches and general managers to try to understand how preseason practice concussions jumped to a five-year high of 45 from 26 in 2016.

The overall number of concussions sustained in practice, including the regular season, jumped to 56 from 32 a year earlier.
