Camp observations: Lions' Carter struggles in 1-on-1 matchups

Lions receiver Jeremy Kerley had a solid outing during the one-on-one and team portions of Monday's practice.

Allen Park -- Here are some notes and observations from the Lions’ training camp practice on Monday:

• At about the midpoint of practice, it started to lightly rain. That quickly developed into a torrential downpour, but it didn't put a halt to the activities. The team continued to practice through the soggy conditions, including full-team scrimmage work in the red zone while wearing full pads.

Coach Jim Caldwell gave little to no consideration moving the remainder of the session indoors.

"We love this," he said. "We’re an indoor team with an outdoor mentality."

• Linebacker Josh Bynes and offensive lineman Geoff Schwartz didn't practice, which is new. Offensive tackle Michael Ola suffered what appeared to be an ankle injury during the practice and had to be helped to the locker room. Safety Don Carey had his knee looked at by a trainer near the end of day.

• In one-on-one work between the receivers and defensive backs, cornerback Alex Carter continued to struggle. All the throws came from the three-yard line and he was beaten by fade routes to both rookie Quinshad Davis and TJ Jones.

Lions' Caldwell: Quarless 'worth second chance'

• Receiver Jeremy Kerley had a good day, both in the one-on-ones and the team portions of practice. His ability to get separation stuck out, both while the field was dry and soaked.  Starting nickelback Quandre Diggs had no chance manning Kerley on an escape route.

• The offensive linemen and defensive linemen also went head-to-head, working the pass-rush drill. Not a great day for rookie Taylor Decker, who was easily bested by both Ezekiel Ansah, on an inside rush, and Brandon Copeland, who powered right through the offensive tackle. Ansah got around Decker so quickly that he dove through the suspended tackling dummy and slid across the wet field on his stomach like a Slip'N Slide.

• Larry Warford continued his strong training camp, getting the best of both Haloti Ngata and Stefan Charles in individual reps. Ngata did get a measure of revenge, coming up with a sack in full team work. On that play, quarterback Matthew Stafford still fired a pass to Marvin Jones down the sideline in the tightest window imaginable. It was a perfect throw and an impressive catch by Jones, who showed superb concentration despite physical, tight coverage by cornerback Nevin Lawson.

• A couple of young tight ends, Adam Fuehne and Orson Charles, joined the pass-rush drill, but were dominated in their matchups against defensive ends.

• Starting guard Laken Tomlinson has had a rough camp, but he dominated his reps against Tyrunn Walker and Gabe Wright on this day.
