Drone work: The Lions were utilizing a DJI Phantom 3 Inspire 1 drone to film a couple portions of practice Sunday. It's the first time the team has utilized drone coverage in a practice that's been open to the media. Head coach Jim Caldwell said after practice it was used more for media purposes, but could also develop into a football application as well. – Tim Twentyman
Quin, sign of the times: There was no way of knowing by Glover Quin's demeanor at the first practice of training camp Sunday that he had signed a contract extension before taking the field. Quin was one of the first players on the field, and he meticulously went through his personal routine to get ready for drills. And late in practice, he sprinted downfield to get in on the play after a receiver had made a catch for a long gain. It was the sign of a true pro. – *Mike O'Hara.
Seeing red: Last year, it was Ameer Abdullah. This year, Theo Riddick put on the "no contact" red jersey to begin training camp. Riddick is coming off wrist surgery, and the move is just a precaution. It's similar to how it was used for Abdullah last year coming off shoulder surgery. Caldwell said it's just a matter of getting Riddick back in the flow where everything feels good consistently and trying to hold back on some of the contact early on. – Tim Twentyman
All hands, young and old: Veteran receiver Marvin Jones Jr. made a good catch early in practice. It was a short route, with cornerback Darius Slay in tight coverage. Jones extended his arms to snatch the ball out of the air. Later in practice, undrafted rookie Noel Thomas reached back to catch a ball near the back of his helmet. – Mike O'Hara
Close but no cigar: Both cornerbacks Darius Slay and Johnson Bademosi dropped interception chances. There's an old joke that players are cornerbacks because they don't have the hands to play receiver. But, for a team that managed just 14 takeaways last year (ranked 28th), and had just 10 interceptions, Detroit's defenders need to haul in more of those chances. It wasn't all bad, however. Cornerback turned safety, Alex Carter, made a very nice ranging interception on a deep pass from Jake Rudock intended for Jared Abbrederis. – Tim Twentyman
Decker's day:Injured offensive tackle Taylor Decker is on the Physically Unable to Perform list while he recovers from an injured right shoulder sustained during the OTA workouts. Decker's right arm is no longer in the sling that he wore during minicamp. Players on the PUP list are not allowed to take part in practice under NFL rules, but Decker was on the field throughout Sunday's practice and visibly engaged with teammates in what was going on. – Mike O'Hara
Punt return duties: Handling punt return duties during the first training camp practice were: Jace Billingsley, Abbrederis, Keshawn Martin, Golden Tate, TJ Jones and Jamal Agnew. – Tim Twentyman
Linebacking trio: Jarrad Davis (MIKE), Tahir Whitehead (WILL) and Antwione Williams (SAM) were the three linebackers with the first team in base defense. When the team went to the nickel, it was Davis, Whitehead and Quandre Diggs (slot). – *Tim Twentyman *
