Detroit Lions 2026 training camp preview: Nickel sets mean more opportunities for CBs

In this installment of our Detroit Lions 2026 training camp preview series, we shift back to the defensive secondary by examining the Lions’ cornerbacks, speculating on current and future roles, and discussing how many players from this group could make the 53-man roster.

• Linebackers: Adapting the LB room

Roster construction

Under the Brad Holmes and Dan Campbell regime, the Lions have fluctuated in the number of cornerbacks on the active roster, typically keeping five or six corners active, but have adjusted the room as injuries piled up. Let’s take a look at what they’ve done at corner in the previous five seasons:

• 2021: Started the season with six, but ended with just five.
• 2022: Repeated the previous season by starting with six and ending with five.
• 2023: The Lions opened and ended with seven, but only kept six active on game days.
• 2024: They started with six and ended with just four, though three contributors finished the season on injured reserve.
• 2025: Opened the season with five corners, but after only a month, injuries mounted, and the room fluctuated between five and seven corners throughout the season, ending with six corners

Starter turnover and Nickel defense

The Lions’ secondary was forced to undergo a series of changes this offseason; some decisions were purposeful, while others were forced upon them.

At outside cornerback, D.J. Reed (10 starts in 2025) returns for 2026, and while he is coming off an injury that cost him nearly two months of the regular season, expectations are that he will enter training camp healthy. Rock Ya-Sin (six starts) re-signed and is expected to open training camp in the starting lineup, as previous starters Terrion Arnold (seven starts) was released following his arrest and Amik Robertson (10 starts) departed in free agency.

Ennis Rakestraw returns for his third season in Detroit, but he is coming off an injury that cost him the entire 2025 season. While he has previously challenged for inside and outside roles, newly acquired Roger McCreary started in the slot during spring practices and is expected to stay in that role entering training camp.

To round out the room, the Lions re-signed special teams ace Khalil Dorsey and Legion-of-whom hero Nick Whiteside, drafted Keith Abney in the fifth round, and signed UDFA De’Shawn Rucker following the conclusion of the draft.

The battleground

Will Rock Ya-Sin hold off challengers?

Following Arnold’s release, the presumption is that Ya-Sin will open training camp as the starter...
