Philadelphia CF Aaron Rowand suffering his second break yesterday after colliding with fantasy stud 2B Chase Utley. (Thank God it wasn't Utley!)
Rowand broke his ankle and will be out 4-6 weeks.
At this point, no fantasy team should hold Rowand's spot for a second longer than it takes to find a viable option.
Maybe he gets back for the end of the year. Maybe he doesn't.
One weeks' worth of stats won't ruin anyone's season.
This advice applies to any and all players who go down from this point forward. There is not enough time to recover.
A team in play-off contention may bring a player back for the last week or so, but I wouldn't count on non-contenders doing so.
