Miami Dolphins rookie cornerback Jason Marshall Jr. has been putting together a strong training camp and preseason so far. But it's his recent emergence in the slot that has coaches and teammates buzzing this week.

A little over a month after announcing his decision to come out of retirement, the Miami Dolphins have activated tight end Darren Waller off the PUP list.

It was a glorified walkthrough training camp practice for the Dolphins, but the secondary had a few snapshots of good coverage, causing sacks or throwaways for QB Tua Tagovailoa.

The Dolphins augmented their cornerback room on Wednesday, adding veteran Cameron Dantzler Sr., who made 26 starts for the Minnesota Vikings earlier this decade but has been out of the league for the past year-and-a-half.

The Dolphins announced the signing of cornerback Cameron Dantzler while also officially adding Judon to their roster on Tuesday. Word of Judon’s agreement to join the team came after a visit on Monday.

Jones is brutally honest, if nothing else. It turns out that he’s learning a new technique with the Dolphins. He’s learning to press at the line of scrimmage. And it’s been an adjustment.

The Miami Dolphins have neglected their backup quarterback situation for years now, but their seventh-round selection in the NFL draft is making waves in camp.
