I wonder what happens in a situation where a player is eligible to report, but a team bars them
https://www.thecubreporter.com/book/export/html/3546Isn't that the suspended list?
The main instance where it is used is when a player is suspended by the league as the result of an on-field incident, but it can also be initiated by the player's own club in the case of unacceptable behavior (such as a player getting into an altercation with his manager, a teammate, or a fan), or a violation of team rules related to chronic tardiness, possession of alcohol or reporting to work intoxicated, missing a doctor's appointment, et al. The Suspended List is used more liberally in the minor leagues, mainly because minor league players don't have the protection of a union.
