Redskins tight end Jordan Reed showed us last week why you should never feel fully comfortable starting players coming back from a concussion until the ball is kicked off and he is on the field. Right now, fantasy owners of Steelers running back Le’Veon Bell should exercise a similar level of caution. Head coach Mike Tomlin said Tuesday that Bell still has some tests to pass following his Week 13 concussion, but he added that Bell “looks good.” FANTASY ANALYSIS: Well, that’s vague, but it could certainly be worse. Bell’s status will be updated Wednesday. He has a favorable matchup versus the Dolphins in Week 14, but if he can’t play, Felix Jones and Jonathan Dwyer would likely split the touches against the seventh-most generous defense to running backs in fantasy.
