Delmas, who was on the physically-unable-to-perform list through the first nine days of camp with a groin injury, said he was happy to be back.
"Today I felt great working out," he said. "The guys are working together well. I came out and warmed up extra early just so if it was kind of sore I wouldn't go out there and have any tweaks so I felt great."
Still, the second-year safety said he will ease back into the normal workouts.
"The coaches are doing a great job making me work back in really slow – starting with position drills and hopefully tomorrow I start out with position drills and then seven-on-seven after that," he said.
Drafted by Detroit with the 33rd overall pick in 2009, Delmas was one of the few bright spots in the team's secondary last season. This year, he feels the additions of veteran Kyle Vanden Bosch and Jonathan Wade will help Detroit's defense.
"Just having guys like that with high energy uplifts us to go out here and practice every day as winners," he said.
According to head coach Jim Schwartz, it's the energy and enthusiasm of Delmas that will make a difference in 2010.
"We missed his personality on the field," he said. "He brings a lot of excitement to our defense. We need to play with his personality on defense."
"It's good to see 26 back."
