The ups and downs from Day 2 of Dolphins training camp.

DAVIE — Here’s a breakdown of the Dolphins training camp practice Friday: Stock up: Was it a coincidence that on the same day the Dolphins signed Allen Hurns to fortify a relatively thin receiver unit Brice Butler, who is projected as one of the better receivers fighting for a spot on Miami’s 53-man regular-season roster, caught a 45-yard touchdown pass from Ryan Fitzpatrick on a deep out?

Butler created separation from rookie cornerback Nik Needham and hauled in the deep floater for the score. Butler, a six-year veteran, must continue making plays such as this to extend his stay in South Florida. Stock down: The last time Kenyan Drake was the featured back of an offense was his high school days at Hillgrove High, and those expecting Miami to put more on his plate this season might be setting themselves up for a letdown.

Kalen Ballage, a 2018 fourth-round pick, has spent the first two practices working with the starters while Drake comes on to the practice field on third downs. The Dolphins could be pacing Drake, who contributed 1,012 rushing and receiving yards and led the team with nine touchdowns last year. But Brian Flores and offensive coordinator Chad O’Shea do come from an offense that typically has tailbacks playing specific roles and rotating in and out of games. Camp observations: T.J. McDonald, who is projected as one of the Dolphins’ starting safeties, came off the physicallyunable-to-perform list and practiced Friday. McDonald rotated in with Bobby McCain and Reshad Jones as Miami’s starting safeties. McCain, who played nickel cornerback his first four years, continues to work exclusively as a safety. Sam Eguavoen, a CFL import, continues to work as the starting inside linebacker in Miami’s nickel package, playing ahead of Kiko Alonso and Raekwon McMillan. … Eric Rowe, who is competing to become the starting cornerback opposite Xavien Howard, rebounded from a tough Thursday practice to have a solid Friday session. Rowe knocked down two passes that would have been touchdowns if the action were live. … Hurns, a sevenyear veteran the Dolphins signed to a one-year deal worth $3 million with incentives, participated during position drills but went to the side to work with the training staff during 11-on-11 periods. … Safety Walt Aikens pulled down an interception during one-on-one drills versus receivers. Injuries: Receiver Albert Wilson, who suffered a serious hip injury last season, sat out Friday’s session, a day after participating in position drills. The Dolphins’ tentative plan is for Wilson to practice every other day while he continues to work his way back from the injury. … Jakeem Grant, who is coming back from a foot injury, continues to be held out of 11-on-11 practice sessions. … Dwayne Allen, a projected starter at tight end, continues to sit out practice as one of three players still on the PUP list. The Dolphins expect Allen to practice in the coming days. … Rookie pass rusher Andrew Van Ginkel was held out of Friday’s practice because of an undisclosed injury. Quote of the day: “It wasn’t bad at all,” Hurns said about getting released by the Cowboys earlier this week, days before signing with the Dolphins. “Once I found out we wanted to go separate ways, my main thing was to find my next destination. I wasn’t stressed or anything. As far as how I am mentally, I’m good. I don’t let too many things bring me down. I was just excited for the next move.”
