The Dolphins made a flurry of minor roster moves Tuesday, cutting linebacker Sammy Brown and terminating the practice squad contract of Chris “7-Eleven” Hogan. They also announced the previously reported additions of Chas Alecxih and Brian Tyms to their practice squad.

Brown’s time in Miami was short-lived. He joined the team via the waiver wire the week before the season began, but did not play in the opener.

With Brown gone, that leaves an empty spot on Dolphins’ 53-man roster, and just 22 players on Miami’s defense.
