I believe it used to be but I think now its much like football, once you have played a second the redshirt is blown. I believe if he was to reinjure himself you could apply for a medical redshirt because of the % of games played would fall under the threshold as roofbeam noted. OrangExtreme is usually good with this type of stuff perhaps he can clarify.
3 games -or- 30% (rounded up), whichever is greater.
14.2.4 Hardship Waiver. A student-athlete may be granted an additional year of competition by the conference
or the Committee on Student-Athlete Reinstatement for reasons of “hardship.” Hardship is defined as an
incapacity resulting from an injury or illness that has occurred under all of the following conditions: (Revised:
8/8/02, 11/1/07 effective 8/1/08)
(a) The incapacitating injury or illness occurs in one of the four seasons of intercollegiate competition at any two year
or four-year collegiate institutions or occurs after the first day of classes in the student-athlete’s senior year
in high school; (Revised: 1/10/92 effective 8/1/92, 11/1/01, 8/8/02)
(b) The injury or illness occurs prior to the first competition of the second half of the playing season that concludes
with the NCAA championship in that sport (see Bylaw 14.2.4.3.4) and results in incapacity to compete
for the remainder of that playing season; (Revised: 1/14/97 effective 8/1/97, 4/26/01 effective 8/1/01,
4/3/02, 4/24/08)
(c) In team sports, the injury or illness occurs when the student-athlete has not participated in more than three
contests or dates of competition (whichever is applicable to that sport) or 30 percent (whichever number is
greater) of the institution’s scheduled or completed contests or dates of competition in his or her sport. Only
scheduled or completed competition against outside participants during the playing season that concludes
with the NCAA championship, or, if so designated, during the official NCAA championship playing season
in that sport (e.g., spring baseball, fall soccer), shall be countable under this limitation in calculating both the
number of contests or dates of competition in which the student-athlete has participated and the number of
scheduled or completed contests or dates of competition during that season in the sport.
