Colts, Panthers, Jaguars open 21-day windows for Key, Brooks, Green

The Colts opened a 21-day practice window for defensive end Arden Key, who has been sidelined by a hamstring injury since October; he was a starter and had recorded 11 quarterback pressures and a sack before going on injured reserve. Carolina also designated running back Jonathon Brooks to return to practice, giving the Panthers 21 days to decide whether to activate him; if reinstated, he is expected to work behind Chuba Hubbard. Jacksonville opened a 21-day window for defensive lineman BJ Green II, who has been out with an elbow injury since Week 1. Green’s return could bolster a Jaguars defense that ranks among the NFL’s least productive in sacks, though his activation will depend on his practice progress.
