Davis sustained a hamstring injury and didn't participate in team drills during Wednesday's practice, Matthew Paras of NOLA.com reports.
Davis, who has made an All-Pro team in each of his last five seasons, appears to have suffered a hamstring injury that could sideline him for the immediate future. The Saints will likely be cautious with Davis' injury, which makes sense considering how crucial he is to the team's defensive success. Once Davis returns to the field, he's expected to remain one of the most impactful inside linebackers in the NFL.
