This article seems to indicate it's a new ankle injury he suffered in his second day back to practice:
Trey Amos is a big part of the Commanders' plans for both the present and future, but he can't escape the injury bug and it's starting to become a bit worrisome.

But it's all really loosy goosy language.
The thing is, he suffered a broken leg. It was never reported that by "broken" it meant "had to be re-attached." So broken leg shouldn't take 8 months to heal.
I would understand if it took some time to get strength back.
My guess is this is something new, but that's strictly a SWAG.
And that doesn't make it better. He needs to get healthy and get and keep his ass out there. I ranked him as the 2nd most indispensable player on the team because of what's behind him. Daniels was first. McLaurin 3rd (this was before Diggs signing), Allegretti 4th because JGG and rookie 6th round pick were behind him, Tunsil 5th because he might be the best player on the team.
And 3 of my top 5 have been out. 5 is done for the year (Tunsil), 2 has practiced once, and 4 is returning to practice this week
Ironically the two guys who missed the most time last year both look great in Daniels and McLaurin.
