Flowers (foot) was a limited participant in Thursday's practice.
Flowers remains on the reserve-PUP list, which gives the Patriots a 21-day window to activate him to the team's active roster now that he's begun practicing, per Aaron Wilson of KPRC 2 Houston. The 30-year-old linebacker has appeared in 79 games throughout his eight-year career, recording 265 tackles, including 31.5 sacks.
