Those six are CB De'Andre Presley, S Jordan Kovacs, C Sam Brenner, WR Brian Tyms, TE Kyle Miller and WR Marvin McNutt.

• The Dolphins began their practice Monday with both of their rookie cornerbacks, Jamar Taylor and Will Davis, working on the side. Worse, Davis was wearing a walking boot over his left foot.
• The news was better when it comes to first-round pick Dion Jordan, who was on the field during a special teams drill and was observed blocking the sled along with his defensive line mates.
• Some jersey numbers to note: Running back Mike Gillislee has switched from 35 to 23; Jelani Jenkins has gone from 43 to 53; and new fullback Tyler Clutts is wearing 40.
