FLOWERY BRANCH, Ga. -- A daily review of the hot topics from Atlanta Falcons training camp:

LIGHT DAY: It was a light practice on Saturday after the Falcons held their "Fight Night Lights" scrimmage. Many of the veteran players rested as the team practiced in shorts. Wide receiver Roddy White didn't even participate, while outside linebacker Kroy Biermann had his scheduled day off. "Today's practice, it was a non-padded practice," coach Mike Smith said. "The guys worked hard last night. We didn't get finished and get back over here to the facility until after 11 p.m. I thought they came back, had a nice walk-through this morning. I thought it was a spirited practice. Again, the effort's been outstanding."

SAFETY OPTIONS: Smith pointed out how cornerbacks Robert McClain and Ricardo Allen got a few reps at safety Saturday. That was planned after projected starting free safety Dwight Lowery suffered a concussion Friday, leaving the team depleted as the position. "We have some guys on our roster right now that we can cross train in terms of some of the corners who will work at the safety position," Smith said. "When we start getting to our 53-man roster, we've got to do that anyway. So, we'll work some of the corners inside."

FIGHT CLUB: The latest fight to break out during practice was between rookie outside linebacker Tyler Starr and rookie tight end Brian Wozniak. "Just a little friendly competition," Starr said. "Guys don't like to get beat on the field out here. Tempers got a little heated. It was what it was. We compete on the field and off the field, it's like nothing ever happened. They took a few swings at each other midway through practice. Some of the others battle have been Kroy Biermann versus rookie Jake Matthews, Stansly Maponga versus Gabe Carimi, and Joe Hawley versus rookie Jacques Smith.

SOMETHING SPECIAL: Special-teams coach Keith Armstrong got after it hard with his unit at the start of practice. Hours before the session, he singled out a few rookies as possible contributors this season. "I'll tell you what: [Prince] Shembo has been a guy that's really jumped out to me in terms of a linebacker standpoint," Armstrong said. "[Bernard] Reedy, the little receiver, has done a nice job for us. Great effort. I like his heart [and] want to. He's got that right attitude. Those would be the two guys right now."

EXTRA POINTS: Kemal Ishmael and Sean Baker did a good job communicating as they received most of the safety reps on Saturday while William Moore rested. ... Tight end Levine Toilolo had a nice touchdown catch while covered during red zone work. ... Cornerback Jordan Mabin was one of the lesser known players that made players Saturday.
