The medical board received 27 petitions late last year. In all, 18 proposed conditions failed to meet statutory and rule requirements for consideration, the committee said.
Among the conditions rejected: being a fan of the Cincinnati Bengals or Cleveland Browns.
The committee will make recommendations to the full board for a vote to adopt or deny a proposal as a qualifying condition. A full board vote is expected this summer.
The Bengals emerged from the 2019 season with a 2-14 record. The Browns finished with a 6-10 record, third in the AFC North. Before the season, some observers thought the Cleveland team could maybe make it to the playoffs, two years after going winless in the 2017 season.
