SAN DIEGO -- A daily review of the hot topics coming out of San Diego Chargers training camp:

Play of the day: Rookie seventh-round draft choice Tevin Reese shook loose on a double move for a 40-yard touchdown against cornerback Brandon Ghee on a pass from backup quarterback Kellen Clemens. The play capped a solid day for Reese, who ran crisp routes and caught the ball well during 1-on-1 drills.

Position watch – Quarterback: Philip Rivers said he liked the tempo the offense played at on Thursday, running plays and in and out of drills at a quick pace.

Rivers said one of the differences from last year to this year is players know and understand what to expect in practice and the meeting room, now that the team is in the second season with head coach Mike McCoy.

“We really practiced fast,” Rivers said. “We had some mistakes. But those things will get ironed out as we progress.”

Injury report: Offensive guard Jeromey Clary (shoulder, hip) remains on the active, physically unable to perform (PUP) list. Clary’s replacement, Johnnie Troutman, had to leave the field toward the end of practice with what appeared to be a hamstring injury. Troutman was replaced by rookie Chris Watt at right guard. Troutman later returned to practice.

Up next: The Chargers practice at 2:50 p.m. on Friday, and hold their first padded practice on Saturday at 9:20 a.m. Both practices will take place at Chargers Park, and are open to the public.

You don’t say: “It feels great. But it’s early. I think that this is one of those injuries that time is going to tell. It’s going to be interesting to see how fatigue affects it. But right now, it feels great.” -- Chargers outside linebacker Dwight Freeney, discussing his return to the field as a full participant after suffering a torn quad that ended his 2013 season. Freeney looked explosive rushing the passer in team drills.

Coach’s corner: The Chargers had a handful of drops on Thursday in both team and 7-on-7 drills. McCoy chalked that up to nerves from the opening of training camp, and expects that area to improve over the next couple of days.

“We talked about that after practice, that we had too many dropped balls,” McCoy said. “It wasn’t just one position. There were a number of different guys doing it, whether it was in individual period or team period, 7-on-7 – things like that. So that’s something we’ve got to clean up.”
