Flowers (hamstring) took part in individual drills at Friday's practice, Jeff Zrebiec of The Athletic reports.
This is the first sign of progress in Flowers' recovery from the hamstring injury that he suffered in the first half of the Ravens' Week 1 win at Indianapolis. Even if he goes down as a limited participant, though, he likely will be listed as questionable, at best, ahead of Sunday's game against the Cowboys in Rio de Janeiro.
