I have an important game, it's a divisional round game against a team who beat me two times this season. My starting RB is questionnable with an arm injury for 3 weeks. I've always benched my questionnable players in favor of an healthy player, but what would you do? Start him or rest him?

My RB #2 on my depht chart is a WR, he's 66 in RB with 100 in ball carrying, 89 in speed, 83 in avoid fumble. He had an avg of 6,4 yards in 53 carries during reg. season and an avg of 7,0 in 8 carries during the wild card playoff game.

Do you think I can be comfortable to rest my RB and start my WR at RB?

It's the playoffs .. play him!

I'd try to limit carries (looks like he averages around 20+/game) .. maybe you could limit to certain key formations? I'm not a personnel rule guy so I don't know if you can or not.

3 games.....Div, Con, SB.
Considering its win to advance and your RB wont even be available for the big game if you rest him, I would use the RB as much as you could and save the backup for the championship. Wouldn't want to risk having two injured RB's
Just my opinion.

Arm injury means more chances of fumbles. Turnovers kill you in the playoffs. Just saying

Thanks. I think I'll start him just because it's the playoffs and if I lose I don't play any more games. Maybe he has more chance to fumble the ball but I'll take the risk.

If a player has zero in a health category there will be a maximum of a 25 percent deduction in abilities pertaining to that specific injury. To me that him playing with a 40 something ability to protect he ball or similar for his catch .

Thanks all. Finally I played him (Gallagher) and he fumbled the ball at the 10 yards line on my first drive, but it was his only fumble. He had 111 yards in 22 carries and 1 TD. It's not him who cost me the game, it was my kicker, who has 100 in accuracy, he missed an extra point and a field goal. I lost 24-20.
