COLUMBUS, Ohio (AP) Injured defensive end Nick Bosa has decided to leave school to focus on getting ready for the NFL draft in the spring, Ohio State said Tuesday.

The junior All-American from Fort Lauderdale, Florida, already had four sacks this season when he suffered a core muscle injury on Sept. 15 in the third game of the season. He had surgery five days later, and no timetable was set for his return to the team.

Considered one of the best players in college football, Bosa had left no doubt that he would leave school after this season to enter the draft. He planned to follow the same path as his older brother, Joey, who left Ohio State a year early and now plays for the Los Angeles Chargers.
