MIAMI GARDENS - The Miami Dolphins had their second training camp practice of the summer on Thursday at Baptist Health Training Complex.

And there may be some big Tua Tagovailoa news brewing.

Here are some observations:

• Tua Tagovailoa, engaged in a contract dispute, did not have a helmet and did not participate. Tua held a football in his left hand and what may have been a listening device in his right hand. He stood behind the huddle but had no helmet. The Tua hold-in is heating up. At what point does this significantly impact the team? Does it in any way accelerate contract talks?

• Linebacker David Long is still working on the side in an orange jersey and is not ready to practice. But he was hitting the blocking sled hard and looks closer.

• One day after a little scare, safety Jevon Holland was participating.

• Jonnu Smith and Terron Armstead were not spotted as participants. Armstead is going to have some veterans' rest.

• Jaelan Phillips was working on the side. Bradley Chubb and Cam Goode continue rehabilitation work.

• Mike White hit Alec Ingold for a long completion.

• Jaylen Waddle made a nice grab over the middle from Mike White.

• Kyler Fuller and Calais Campbell appear to have had a veterans' rest day.

• Running back Chris Brooks fumbled recovered by Isaiah Mack. Brooks later dropped a pass.

• Channing Tindall has a pass break up.

• Emmanuel Ogbah wore an orange jersey as player of the previous practice.

• Pass rusher Quinton Bell is off to a nice camp start.

• Center Ireland Brown had a bad snap. It was the second straight day a Dolphins' center had a bad snap. Yesterday it was a fumbled exchange involving Jack Driscoll.

• Emmanuel Ogbah, wearing #51, had a sack.

• Elijah Campbell intercepted Mike White.

• Kader Kohou had two pass breakups.
