The NFL is considering not extending an invitation to the Combine to players who are academicaly ineligible in college, according to CBSSports.com.
CBS's source said the move is being discussed as a result of increased concern with the maturity and commitment of prospects entering the NFL. If the measure were in place for the 2013 Combine, a considerable number of players would not have been invited to Indianapolis for the Combine.
NCAA academic eligibility regulates a student-athlete's coursework completion and GPA. From the NCAA's website:
In Division I, student-athletes must complete 40 percent of the coursework required for a degree by the end of their second year. They must complete 60 percent by the end of their third year and 80 percent by the end of their fourth year. Student-athletes are allowed five years to graduate while receiving athletically related financial aid. All Division I student-athletes must earn at least six credit hours each term to be eligible for the following term and must meet minimum grade-point average requirements that are related to an institution’s own GPA standards for graduation.
