Jessie Lemonier, a former NFL linebacker who played for the Los Angeles Chargers and Detroit Lions, has died at age 25, the teams announced. Neither organization released a cause of death for Lemonier, who recorded 17 tackles and 1.5 sacks in 13 career games. Lemonier and his girlfriend were expecting a baby together, his agent, Drew Smith, told ESPN. “Jessie was a model teammate and wonderful young man who is gone far too soon,” the Lions said Thursday.
