wow that sucks. hope he heals up soon.
That is a downer. That must be one vicious groin injury. But kickers are funny, that kind of injury if it does not heal properly can affect the kicker for years.
I think that is something like what happened to Nick Folk. He was Bailey-level accurate his first year, got hurt and then was lousy thereafter.
I hate it, but sit him as long as you have to. If scoring 3 points to win a game is consistently that big of a deal, you are not going anywhere in the playoffs.
