Ouch! Just suffered my first ever training-related injury.... bound to happen....

It's a really nice young player I picked up yesterday.... don't ABSOLUTELY need him this
season... but he'll be a great asset next year... so I thought.... if I'm not going to use him in
the squad.... how about a little experimental power training.... d'oh! Oh well....

now the question is.... let him rest the 4 days or shorten it a bit with packs to get him back training?
Kinda feel like I should save packs for active players...
