What happened: Coach Kellen Moore confirmed the diagnosis Tuesday. New Orleans placed Chandler and tight end Moliki Matavao on season-ending injured reserve.
Why it matters: Alvin Kamara is sidelined with an MCL sprain, while Devin Neal is dealing with a hamstring injury. The Saints traded for Zamir White this week to reinforce the depleted backfield.
By the numbers: Chandler spent the previous four seasons with Minnesota but appeared in only three games last season.
What to watch: New Orleans will work White into the rotation while tracking Kamara and Neal through the rest of the preseason.
