METAIRIE, La. -- New Orleans Saints safety Julian Blackmon (shoulder) is likely done for the year, coach Kellen Moore said on Monday.
Moore said that Blackmon's injury "will be a long one, potentially for the full season."
Blackmon, who signed with the Saints during training camp after Tyrann Mathieu retired, played every snap in the Saints' loss to the Arizona Cardinals on Sunday. Moore said the issue was not discovered until a few hours later when Blackmon got home.
"That's what adrenaline does to you," Moore said. "I mean sometimes those things happen for these guys.
