HBO hasn't even set up shop yet, and already, the Miami Dolphins are involved in some, well, "Hard Knocks."

Omar Kelly of the South Florida Sun-Sentinel tweeted that a pair of fights broke out during Wednesday's OTA work. One involved veteran tackle Jake Long against rookie Olivier Vernon.

The other fight involved guard Richie Incognito, notorious for being one of the NFL's most aggressive style players, against  Ryan Baker.

Perhaps HBO is taking notes, hoping the action will heat up even more as the contact heats up.
