The Dolphins are working out veteran cornerbacks on Tuesday, including former Bucs star Alterraun Verner, Ian Rapoport of NFL.com tweets. Tony Carter, best known for his time with the Broncos, is also among those auditioning. 
Verner worked out for the Jaguars back in May, but the Jags passed in part because of his poor conditioning. Months later, one would hope that Verner is back in football shape. Verner was regarded as one of the better cornerbacks in the NFL a few years back when he signed a four-year, $25.5MM deal with the Bucs in 2014. Unfortunately, the 28-year-old never lived up to that big money contract while in Tampa Bay.
Verner and Carter can both play the slot and Miami may see them as potential alternatives to Bobby McCain. Overall, cornerback is one of the Dolphins’ thinnest areas. The Dolphins project to start Byron Maxwell and rising sophomore Xavien Howard with converted wide receiver Tony Lippett, third-round pick Cordrea Tankersley, and McCain in support.
It was expected that Miami would look into cornerbacks before the start of training camp, but one has to wonder if the Dolphins will also kick the tires on some backup defensive tackle options. It has been said that rookie defensive tackles Davon Godchaux and Vincent Taylor are too raw right now to be counted upon as rotation players. The Dolphins took a look at Roy Miller last week, but they did not sign him after the workout.
