The Los Angeles Rams have called up outside linebacker Darryl Peterson III and cornerback Cam Lampkin from the practice squad for Sunday’s Week 4 game at the Philadelphia Eagles.
The elevations, announced Saturday, give Los Angeles two extra bodies on the game-day roster for a trip to Lincoln Financial Field, where the Rams enter at 1-2 and the secondary is already thin.
Peterson, 23, is still waiting on his first regular-season snap. The Akron, Ohio, native played at Archbishop Hoban before spending five seasons at Wisconsin, from 2021 through 2025.
He appeared in 53 games for the Badgers, started for two years, and finished with 139 tackles, 24.5 tackles for loss, 14 sacks, and seven pass breakups.
After going undrafted in April, he signed with Los Angeles as a free agent, was waived in the final cutdown on August 30, and returned to the practice squad the next day.
Listed at 6-foot-1 and 260 pounds, he is the older brother of Darryn Peterson, the guard the Utah Jazz took second overall in the 2026 NBA Draft.
An elevation does not guarantee he dresses and plays, but it is the first real opening he has had to get onto an NFL sideline.
Lampkin’s path is longer and more familiar inside the building.
The Washington State product, from Mesquite, Texas, joined the Rams as an undrafted free agent in 2024 and has bounced between the practice squad and brief active-roster stints ever since.
He is 25, listed around 5-foot-11 and 176 pounds, and was waived again at the end of training camp this summer before clearing waivers and signing back with Los Angeles on August 31.
Teams can elevate a practice-squad player only a limited number of times before they must sign him to the 53-man roster if they want him available again, so repeated call-ups are as much a roster-management tool as a reward.
The timing fits the injury report. Cornerback Jaylen Watson and defensive tackle Aaron Donald are both out against Philadelphia, and tight end Terrance Ferguson is on injured reserve with an ankle sprain.
Lampkin is the more obvious fit as corner depth behind a group that already lost a starter for the week. Peterson supplies edge depth on a defense that will be without its longtime interior anchor.
Neither move changes the starting lineup. Both are standard standard-elevation calls, the kind clubs make when the opponent is the defending conference champion and the active roster is already missing pieces.
Whether either player sees the field will depend on how the game unfolds in Philadelphia.
