At this point, he should seriously consider staying in for his final season. His draft stock is going to take a serious hit after this injury. He's better off rehabbing and returning to play another year and try to re-establish himself as the top QB, although that may be tough as the 2021 class is shaping up to be stacked at QB. He'll also run the risk of injury again but at this point, he may have to take that chance.tua might not come out for 2020 draft, big red flag injury prone. lol
