6 years agoIndianapolis Colts running back Marlon Mack remains in the NFL concussion protocol as of Wednesday afternoon. Unfortunately, with this type of injury, there is no set way to tell if he will be able to return on Sunday. Previously against the Jacksonville Jaguars, he put up quiet numbers, but he has the ability to have a solid game this weekend. Head coach Frank Reich does a great job of putting his best players in a chance to succeed. Due to injuries to other NFL running backs, Mack is a near must-start this weekend if he's active. His speed gives him the ability to have a big game with just one play. If he clears the protocol by Sunday, you should insert him into your lineups.--Gage Bridgford - RotoBaller
