While the official start isn’t until July 27 for the Miami Dolphins, their rookies will report to training camp on July 20. Not only did the Dolphins select seven rookies in this year’s draft, but the team also signed 14 rookie free agents shortly after the draft.

Here are the 21 rookies that will report to Davie on Thursday:

Charles Harris, DE

Dolphins selected Charles Harris with their 22nd overall pick in the first round of the draft. Harris will join a defensive end rotation that has Pro Bowler Cameron Wake, Andre Branch and William Hayes. At Missouri, Harris recorded nine sacks and 12 tackles for loss in 2016.

Raekwon McMillan, LB

Raekwon McMillan played middle linebacker at Ohio State, but he will likely play as an outside linebacker with the Dolphins. In his junior season at Ohio State, McMillan racked up 102 tackles, seven tackles for loss and two sacks.
