Miami Dolphins running back Jay Ajayi has been cleared from the league's concussion protocol.
Ajayi returned to practice Sunday after being diagnosed with a concussion Aug. 2. The 2016 breakout rusher played the final 15 regular-season games and lone playoff contest after being left at home for the season opener against the Seattle Seahawks.
Backup running back Kenyan Drake, however, has been placed in the concussion protocol, reports Adam Beasley of the Miami Herald.
Drake rushed four times for 21 yards in the Dolphins' first preseason game, against the Atlanta Falcons.
