Saints running back Alvin Kamara is expected to miss at least one month with a sprained MCL, according to ESPN's Adam Schefter. Kamara suffered the injury during a joint practice with the Cowboys on Tuesday.
Per NFL Trade Rumors, citing Nick Underhill of New Orleans Dot Football, Kamara avoided a major knee injury in the incident. CBS Sports noted that Kamara is set to miss Week 1 for just the second time in his career.
