The NFL is finalizing plans for a summit to continue discussion about player safety. The meeting is planned for May 1-2 at league headquarters in New York and will include a focus on the future of the kickoff.

It remains highly doubtful that the kickoff would be eliminated for the 2018 season.

A league-record 291 concussions were diagnosed last season.

The league's competition committee called for action after receiving data that showed concussions were five times more likely to occur on kickoffs than other plays, even after a series of minor rule changes designed to reduce returns.
