Landry, 26, missed the final seven games of the season with the Achilles' issue and was placed on season-ending injured reserve Dec. 13.
The promising young safety finished the season with 85 tackles, one sack and one interception in nine starts. He led NFC safeties in Pro Bowl votes when placed on IR, according to The Post.
"I'll say (the Achilles' tendon is) about 90 percent," Landry told the newspaper. "I won't say 100 percent because I don't know what kind of endurance I have in it, but as far as how it feels, it's doing good.
"I haven't started running, but I'm back to doing everything with my legs; squats and everything like that. I'm working out just like I used to other than my left side. I obviously can't grab a dumbbell with that side, but I'm doing single-arm bench presses."
