Miami Dolphins quarterbacks coach and passing game coordinator Darrell Bevell suffered a detached retina in late July that forced him to lie face down for 90 percent of the time over straight days.
Jori Epstein of Yahoo! Sports relayed that news amid her article on Bevell's work with Dolphins signal-caller Tua Tagovailoa.
Per Epstein:
"Bevell was watching film around 11 p.m. on July 30 when he realized his vision was impaired. He covered his right eye: no problem seeing tape or the ceiling. He covered his left: His right eye didn't afford him the same clarity.
