Similar thing happened to my center last season. 33 years old and lost skills in IS, ID, and RB... (not in the same week though) So at the end of the season, I basically paid $35k for a $25k player...
I bet you will be back by the end of this season ;)
I will wait till I get kicked out of the cup, to decide what to do with my older players.
Maybe everyone else decides on a rebuild and I can promote by default?
