RED Light issues:
Indicates a serious medical issue that should cause a team to stop and reassess. These players aren’t undraftable, but their draft position will likely be affected by the evaluation of team doctors. When a player is red flagged, it doesn’t mean he can’t play football. It just means there is an issue to cause a team to stop and pause. Usually an "red M" goes on the players draft board magnet as a reminder. A general manager will have a long discussion with his medical staff prior to a final decision. They may need surgery, be recovering from surgery or have significant longevity issues. One or more teams will likely have taken these players off their draft boards due to medical risk while others will be willing to take a risk based on need or value.

Indicates a significant medical issue that needs to be taken into account. As the color indicates, a general manger needs to slow down and factor in his team’s medical assessment. As a reminder, typically a "yellow M" is placed on the players draft magnet. If two players are rated the same, it might be less risky to select the non-yellow light player.

GREEN Light issues
