But wouldn't this mean he/she would have to sit out since if he/she is a walk on they obviously played and practiced with the team?Not sure if you are still looking for the answer but I found this so I think the answer is yes:
Non-recruited Student Exception
A student-athlete may transfer and play immediately if he or she met the following conditions at the first institution:
[ ]The student-athlete was not recruited according to the NCAA’s definition of recruiting;
[ ]The student-athlete never received an athletic scholarship; and
[ ]The student-athlete did not practice or compete at all in athletics at the original school except for one 14-day period (i.e. a tryout).
