Injuries are always around this game and it is part of the game. When you make a commitment to a player, you are aware of that. So, it is part of the risk, mostly when you make a commitment like they did to Porcello. Ells, Buch, Materson, etc are injury prone players. I don't think it is the case of Porcello, but you never know when an injury could start, mostly at SPs.
Don't worry YTN, maybe in other occasion we bet, no big deal.
