Graham injured his foot late in Sunday's game against the New England Patriots, and had to go to the sidelines to get it taped up. He did return to the lineup after medical attention on the sideline, but had to leave the game again and did not return.
On Monday, Graham had an MRI, which had to have gone well for the Saints given this report. The bye week comes at a good time for New Orleans given the injury, as it would be a huge loss if Graham misses any time. He's the NFL's leading receiver, even after being held without a catch against the Patriots. He has 593 yards and six touchdowns on the season.
The Saints suffered their first loss of the season against New England, but have an easier matchup against the Buffalo Bills when they return from the bye week. The following week, they face the New York Jets, and don't face one of the "better" teams in the NFL until they host the San Francisco 49ers in Week 11, so taking it slow with Graham is certainly an option.
