Washington commanders did not participate in the exercise. Instead, 

the 3rd-year pro stood on the sidelines with his right hand in a clear brace and sling.

It is unclear what the extent of Curl's injury was.

Head coach Ron Rivera was silent about Curl's condition after practice.

According to ESPN's John Keem, Rivera said, "We don't have to report 

the injury until next Wednesday, so we'll stay away from all of that."

However, Curl's teammate and fellow safety Bobby McCain told JP Finlay

of NBC Sports Washington that Curl "will be out for a few days."
