Lattimore left for the locker room after colliding with teammate A.J. Klein while trying to make a tackle. The 2017 Defensive Rookie of the Year was examined in the sideline medical tent before walking slowly under his own power to the locker room to be evaluated.
Lattimore is one of the premier young corners in the NFL. As a rookie, he recorded five interceptions and 43 tackles. This season, he's recorded 13 tackles through three games.
The Saints are heading into their bye week, so there's a chance Lattimore will clear concussion protocol ahead of New Orleans' next game on Oct. 21 against the Baltimore Ravens. If he can't play, the Saints likely will give plenty of playing time to Justin Hardee, who put in a solid performance against the Redskins.
