LSU star wide receiver Ja'Marr Chase has informed the team that he is choosing to opt out of the 2020 college football season to concentrate on his professional career, sources close to the situation told CBS Sports. A formal announcement is expected Monday with Chase, the nation's top returning wideout, declaring for the 2021 NFL Draft. "It's 100% happening," a highly-placed source close said Sunday. Sources said Chase's decision is not specifically related to the COVID-19 pandemic. Rather, it is believed agents may have simply convinced Chase to leave before his third collegiate season. NFL rules state a player cannot be drafted until three years after his high school graduation. Chase, a rising junior, will become the most notable college football player to opt out of the 2020 season. The unanimous First Team All-America selection set SEC records last season for touchdown catches (20) and receiving yards (1,780). He won the Biletnikoff Award given annually to the nation's best receiver.
