DAVIE, Fla. -- What a day.
One practice. Seven transactions.
By the time the Miami Dolphins took the field for their 5 p.m. practice, they had tweaked their 80-man roster quite a bit.
Here's the rundown of today's announcements:
Signed two second-round draft picks, QB Chad Henne (he's on the field after missing this morning's pratice) and DE Phillip Merling, free-agent WR Anthony Armstrong and free-agent G Rueben Riley.
Released WR Justin Wynn, T Dan Gore and T Julius Wilson (whose camp ended after one practice).
