David Montgomery has rib cartilage injury

Lions HC Dan Campbell said Monday that RB David Montgomery is dealing with a rib cartilage injury. "He's got a little something in there with cartilage, and he's probably going to be down for a little bit here," Campbell said. "I don't know how long. At his position it's not an easy thing to deal with so we'll just take it as it comes, but I think there's a chance we won't have him for a little bit." Campbell also said that he doesn't yet know if Montgomery will need to go on IR, according to Tim Twentyman of the team's official website. We'll see about that, but it sounds like Montgomery is dealing with a multi-week injury.
