Dolphins practice report: Rookie CBs ailing

DAVIE, Fla. – The Miami Dolphins hit the practice field for the first time during the 2013 regular season. Miami will travel to play the Cleveland Browns on Sunday.

Here are some Dolphins notes from Monday's practice:

  • Miami had full attendance in preparation for Week 1. However, Miami rookie cornerbacks Jamar Taylor and Will Davis worked on the side with trainers in the portion of practice open to the media. Taylor has been off and on with hernia and groin injuries. Davis had a boot on his left foot, which is never a good sign with a game just six days away. That provides insight into why Miami kept extra defensive backs on its 53-man roster.

  • As far as good news, Dolphins No. 3 overall pick Dion Jordan participated in team drills Monday. Jordan (shoulder) returned to full practice last week, which is a sign he's making good progress. Jordan appears confident he can play in Sunday's regular-season opener against the Browns. His role would likely be as a third-down pass-rusher if Jordan plays for Miami.

  • Dolphins tight end Charles Clay remains with the first team. Miami is still searching for a tight end to emerge after the season-ending knee injury to starter Dustin Keller. Clay sat with many of Miami’s starters last week in the fifth preseason game.

  • Two Dolphins rookies changed their numbers after making the 53-man roster. Running back Mike Gillislee changed from 35 to 23, which is the number he wore at the University of Florida. Fellow Gators alum and rookie linebacker Jelani Jenkins also changed his number from 43 to 53. Jenkins took the number of former Dolphins veteran linebacker Austin Spitler.
