The Facts: According to CBSSports.com's Jason La Canfora, the Colts initial sense is Marlon Mack will miss a few weeks with a manageable hamstring strain though they are still waiting final confirmation.

Diehards Line: If healthy, Mack is in line for a major role on what should be a much-improved offense. That said, Jordan Wilkins and Nyheim Hynes both have a chance to be major contributors as well -- and whatever time Mack misses this month will give both rookies a chance to better position themselves for regular-season roles.
