Did Talan get hurt at Notre Dame? Or some other time?
At ND. He started the 6th inning of the Sunday game, and after getting his 2nd K of the inning, he was removed from the game for what appeared to be some sort of injury.
To answer the earlier question, the redshirt rule was changed for football, but Div 1 baseball has always had very strict rules. Playing in just 1 game can lose your redshirt status, unless it is due to an injury. If you have a season-ending injury that occurs in the first half of the season, and you have played in less than 30% of your team's games, you are eligible to redshirt. Otherwise you are SOL. At least that is my understanding of the rules.
Obviously that all changes if the 5 for 5 rule is implemented.
