While still active as a professional football player ahead of the 1938 NFL season, Grant was killed in a lightning strike while golfing.

[5] Grant would start a majority of games each season for the duration of his career at his designated position,[5] but would sometimes come off the bench as a reserve, depending on health and the strategic needs of the team.

Grant's career came to an abrupt end on August 6, 1938, shortly before the start of Giants training camp for the 1938 NFL season.

Playing golf as part of a foursome on a local course at Dedham, Massachusetts, a thunderstorm broke out while the group was walking the fourth fairway.

[2] A bolt of lightning directly hit the footballer, with his caddy suffering burns on his foot and being thrown 15 feet by the force of the blast.
