Quarterback Ryan Tannehill officially signed with the Dolphins and the eighth overall pick took part in his first training camp practice Sunday.
Tannehill had been working out at IMG Performance Institute in Bradenton, Fla.
"I was hoping I could get it done on my birthday," said Tannehill, who turned 24 on Friday. "That would have been a great birthday present. Unfortunately, it had to happen one day later. At the end of the day, this is a business and now I've got the business aspect out of it for the next few years and I'm ready to go out and play football."
Veterans David Garrard and Matt Moore are expected to compete for the starting job to open the season, although Tannehill could insert himself into the mix.
The rookie had a solid camp debut Sunday, working with the second team.
"I thought he'd be a little bit rusty today, but I thought he was pretty much on task on just about everything he did," said Dolphins offensive coordinator Mike Sherman.
Sherman plans on giving Tannehill time with the first team once he gets up to speed.
"I definitely don't feel like I fell behind as far as fundamentals, throwing the ball, conditioning or physically," Tannehill said of missing the first few days of camp. "I want to be here. I want to compete and, so, it was a long two days just sitting around waiting."
