It’s no secret the Miami Dolphins haven’t been happy with the lack of production from their defensive tackles minus All-Pro Ndamukong Suh. Miami ranked 30th in the NFL in rushing defense last season, as they gave up an average of 140.4 rushing yards per game.

Despite drafted two defensive tackles in this year’s draft, it seems the Dolphins are still looking to upgrade their unit.

Jacksonville Jaguars beat writer for First Coast News, Mike Kaye tweeted on Thursday that the Dolphins recently worked out defensive tackle Roy Miller. Last month, Miller told Kaye that some teams have shown interest in the 6-2, 318 pounder.

“There’s a few teams that have shown some interest here and there,” Miller said. “I believe my agent has a few – there’s a couple of trips I have to take – this month. It was always [the plan] to kind of wait until mid-July, so I can go out there with enough time to heal and time to get back in shape and then go out there and compete.”

Miller spent four seasons with the Jaguars and was one of their better defensive tackles. But that was before he missed 10 games last season with a torn Achilles tendon.

In 2016, Miller appeared in six games as he recorded 10 tackles. In his four seasons with the Jaguars, Miller tallied 72 tackles and five sacks.
