It’s clear to anyone who watches college football that the transfer portal has become an absolutely massive part of the game in recent years as more players are choosing to change schools than ever before in the sport’s history. And the NCAA has just made some rule changes to help cut down on the number of players entering the transfer portal.

While players entering the transfer portal for the first time will be able to do so freely and receive immediate eligibility at their next destination, the NCAA is cracking down on players entering the transfer portal multiple times, listing specific guidelines a player must meet in order to receive immediate eligibility following their second transfer.

Under the new rules, a player can receive immediate eligibility at their next destination if they are transferring due to a physical injury or mental health condition, according to CBS Sports. The NCAA will also consider “exigent circumstances” like sexual assault or abuse. But the NCAA will not consider academic circumstances or athletic reasons, such as playing time.

Additionally, these rules only apply to undergraduate players. Players who graduate from an institution will still be allowed to freely transfer to a new program and receive immediate eligibility.
