Roy Lopez, a 28-year-old defensive tackle, is leaving the Detroit Lions after one season to sign a two-year, $11.5 million deal with the Arizona Cardinals. Despite playing a backup role, Lopez had a standout 2025 campaign, outperforming several of the Lions' starters in sacks, quarterback hits, and tackles for loss.

Why it matters

Lopez's departure is a loss for the Lions, who saw him emerge as a disruptive force on their defensive line last season. His return to the Cardinals, where he previously played, provides them with an experienced run-stopper and pass-rusher to bolster their front seven.

The details

In his lone season with the Lions, Lopez played fewer snaps than starters DJ Reader, Tyleik Williams, and Alim McNeil, but still managed to surpass them in several key statistical categories. His strong performance and versatility earned praise from the team's defensive coordinator, Kelvin Sheppard, who highlighted Lopez's athleticism and first-step quickness.

  • On March 9, 2026, Lopez agreed to a two-year, $11.5 million deal with the Arizona Cardinals.
  • In the 2025 season, Lopez played for the Detroit Lions on a one-year, $3.5 million contract.

What they’re saying

“He doesn't get the credit that he deserves as far as his athleticism and his first step quickness. He's been phenomenal and you're talking about ultra-team guy, selfless. … He doesn't care if he plays one or 50 snaps, he's going to make the most of his opportunities.”

“I love this place for what it did for me as a person, as a player. I've grown so much being here.”

The takeaway

Roy Lopez's move from the Lions to the Cardinals highlights the value of versatile defensive linemen who can make an impact in both the run and pass game. His growth in Detroit showcases the potential for players to develop and expand their skillsets, even in backup roles.
