Nebraska linebacker Sean Fisher decided it's time to turn his attention to medical school.
The Millard North graduate announced Monday that he does not plan to return for a possible sixth season with the Huskers in 2013, according to a university news release.
He had considered spending a sixth year in the program, assuming he would've received a medical hardship -- which was likely.
"The opportunity to be part of this football program the past five years has been a great experience and one that is difficult to walk away from, but I made the determination it was time to move on," Fisher said in a formal statement. "I am planning to enroll in medical school in the fall and am putting all my energy toward preparing for that.
"I appreciate Coach (Bo) Pelini and the coaching staff leaving the door open for me to consider returning to football and giving me the time to finalize my decision."
Reached Monday by the Journal Star, Fisher declined further comment.
The 6-foot-6, 230-pound Fisher appeared in all 14 games this season, starting five, and finished with a career-high 48 tackles, including three for loss. He had one tackle in the Capital One Bowl.
Fisher played in one game in 2008 as a true freshman before a shoulder injury sidelined him for the remainder of the season. He missed the entire 2010 season after suffering a leg injury in preseason drills.
In December, Fisher was named a second-team Academic All-American for the second straight year. He maintained a perfect 4.0 cumulative grade-point average in business administration/pre-medicine.
