With starting RB Jay Ajayi sidelined with a concussion, the Miami Dolphins been giving more carries to former Alabama RB Kenyan Drake in recent days.

However, at practice on Monday, Drake suffered a head injury of his own and may miss some time.

According to Adam Beasley of the Miami Herald, Drake took a hit to the head from Torry McTyler and was dazed as he was helped from the field:

As a rookie in 2016, Drake carried the ball 33 times for 179 yards and two touchdowns. He was also an important factor in the return game, fielding 13 kickoffs and returning one for a touchdown.

After practice, Miami coach Adam Gase did not have an update on Drake’s condition.
