Observations from Day 1 of the Detroit Lions 2025 training camp include notes on Tate Ratledge, Christian Mahogany, and Ian Kennelly.

The Detroit Lions held their first training camp practice of the 2025 season on Sunday, and while most things played out as expected, there were several injury updates and a few surprises on the depth chart.

With this being the first practice of the acclimation period, the Lions were not in pads, and practice lasted only an hour and a half, which should be the shortest practice of training camp. Per NFL guidelines, the Lions can expand practices by 15 minutes over each of the next four practices, culminating in a Saturday practice—when season ticket holders arrive—that will likely be two and a half hours in length with the option of wearing shells under their jerseys. After a mandatory day off on Sunday, the Lions will return on Monday, potentially in pads and in front of the general public.

Participation report

Players' participation levels in practice at this time of year can fluctuate day-to-day. Sometimes players are given rest days if they push things too hard the day prior, others work their way off pre-camp injury list (PUP and NFI), while others are dealing with new bumps and bruises.

In case you missed any of the activity, we have multiple articles on Sunday’s roster movement, including:

Most of the players on the PUP/NFI lists were present for practice and watching from the sidelines, including Decker, Alim McNeill, Malcolm Rodriguez, Khalil Dorsey, Miles Frazier, and Stantley Thomas-Oliver. Additionally, Pittman was working off to the side with trainers and told Pride of Detroit that he expects to practice on Monday.

First look at the new offensive line

“We need some guys to step up for us (on the offensive line),” coach Dan Campbell said at his morning press conference. “It’s a great opportunity. We lost Frank (Ragnow), and (Kevin) Zeitler’s gone. So, we have two or three more spots there for guys to step up and help us. And once that happens, then mesh. The guys that we know we can trust, this is where they’re going to play, and then getting whoever those five are together to where they start working together and start trusting each other.”

Here’s a look at how the Lions' offensive line lined up during their 11-on-11 practice segments:

LT Dan Skipper
LG Christian Mahogany
C Tate Ratledge
RG Graham Glasgow

With starting left tackle Decker out through the Hall-of-Fame preseason game, the Lions turned to veteran Skipper for first-team reps at left tackle, put position-flexible second-year OL Mahogany at left guard, continued to play rookie Ratledge at the pivot,...
