The Detroit Lions have won back-to-back NFC North Division titles and cemented themselves as a Super Bowl contender over the past two seasons.

GRAND RAPIDS, Mich. (WOOD) — Injuries on defense was the Lions’ fatal flaw last year. So far, it’s not looking any better this go around. Training camp opened for the Lions Sunday and kicked off with an announcement that defensive tackle Levi Onwuzurike will miss the entire season with a knee injury.

The Detroit Lions have released former Georgia Bulldogs cornerback Divaad Wilson just a few months after signing him. After moving on from Wilson, Detroit signed former Kansas City Chiefs, Carolina Panthers and Los Angeles Chargers cornerback Dicaprio Bootle.

In O'Connor, the Lions found a reliable member of their rotation last season. Picked up during training camp, he earned a practice squad spot to start the regular season before winding up on the active roster and playing a key role midway through the year.

Detroit’s defensive line just took a big hit before the season even started. Lions defensive tackle Levi Onwuzurike is officially out for all of 2025 after undergoing surgery to repair a torn ACL, head coach Dan Campbell confirmed at the start of training camp on Sunday.

Detroit Lions wide receiver Amon-Ra St. Brown earned a spot in a recent ranking of the top-50 players prior to the 2025 NFL season. The former USC standout remains a cornerstone for the Lions offense and is poised for another elite year.
