FLOWERY BRANCH, Ga. -- The Atlanta Falcons returned to practice after a day off and were without rookie running back Tevin Coleman, who sat out with a hamstring strain.

Falcons coach Dan Quinn said he hopes to have Coleman back soon, but did not provide an exact timetable. Of course, Coleman is engaged in a running back competition with Devonta Freeman for the starting role, although Freeman entered camp as the unquestioned leader.

Meanwhile, the Falcons had their struggles on Day 5 of camp. The ball was on the ground more often than not. Bad snaps and tosses appeared to contribute to the miscues.

"Anytime you put the ball on the ground that much, that's our No. 1 goal is to protect the football, and get it on defense," center Joe Hawley said. "So, the defense won today on that. As easy things as center-quarterback (exchange) and holding on to the ball."

Quinn praised his team's overall effort but was naturally disturbed by the mistakes. There were a handful of penalties, too.

"That's one of the things, from an error standpoint, we can totally control that, so we own that," Quinn said. "It wasn't necessarily where the defensive player made a play on that. They were going for it -- the defensive guys were -- but the ones that were on the ground, certainly something we can control. Definitely have to shore that part up."

A few quick-hitters from Day 5 of training camp:

• There was plenty of mixing and matching along the offensive line again. Rookie Jake Rodgers worked with the first team at right tackle with Ryan Schraeder battling a right hamstring strain and Tyler Polumbus watching from the sideline with an undisclosed injury. The first-team combination at one point included Jake Matthews at left tackle, Chris Chester at left guard, Mike Person at center, James Stone at left guard, and Rodgers at right tackle. Starting right guard Jon Asamoah had an upset stomach and didn't finish practice. Quinn said the team wants to get a closer look at the versatility of some of the linemen.

• Freeman was a red-zone target twice for touchdowns, which emphasized how much the Falcons like what he brings to the passing game.

• Rookie receiver Justin Hardy got an earful from offensive coordinator Kyle Shanahan about route-running during a drill.

• Tight end Levine Toilolo impressed with his pass-catching. Quinn also singled out Toilolo for what he's shown as a blocker in the running game.

• First-team outside linebacker Brooks Reed remained sidelined with a groin/hip injury and defensive lineman Cliff Matthews (ankle) also didn't suit up. First-team weakside linebacker Justin Durant was back in action after a couple days off.

• Undrafted rookie tight end Beau Gardner went down with a knee injury after being hit during a drill. Quinn had no immediate update on Gardner's status.

• The music playlist included Coolio ("Gangsta's Paradise"), The Beastie Boys ("No Sleep Till Brooklyn"), and George Clinton ("Atomic Dog").
