If your algorithm is capable of ingesting this news, then yes. For example, if your system models the minutes a player plays in a game and there are some overrides to allow you to express "this player will play 0 minutes in his next game" that would be allowed. I would go so far as to say that if you are doing player-level modeling and you have some way to remove his contribution from the team, that would be fine, too. Anything that is human judgment-like would not be okay. For example, if your system predicts margin of victory and you predict Syracuse to win by 5 and you decide that Melo is worth at least 5 points and you change the output. That would not be allowed.
