Dante Fowler Jr. didn't miss a game in three years of college.
The former Florida star likely will miss his entire rookie year in the NFL.
The Jacksonville Jaguars defensive end, the third overall pick in last week's NFL draft, is likely out for the season after tearing a knee ligament during his first practice.
Fowler tore the anterior cruciate ligament in his left knee during rookie minicamp Friday. ESPN first reported the extent of the injury.
The injury looked serious live and appeared even worse in video replays. Tests revealed the extent of the damage.
