For the last, oh, decade, it was pretty clear what an injured player needed to do to play in a game for the Giants.
Practice.
That's long been Tom Coughlin's guideline (since it sometimes was bent, it's hard to call it a rule). And it was fairly simple to determine when that happened. If a player wasn't on the field Wednesday, that didn't necessarily mean anything. If a guy missed Wednesday and Thursday, it was time to be concerned. Missing all three was the kiss-off and usually resulted in being ruled out on that afternoon's injury report.
