Age and NCAA eligibility

Back in the '80s, a person could not participate in NCAA Division I sports after they had reached the age of 25 unless they had spent time in the Armed Forces or missionary duty. I just heard that the quarterback for FSU (Wuehrful?) is 28 – advanced age for a college senior because he spent time in major league baseball, not armed forces or missionary duty. When did the rule change and what is it now?
