The Las Vegas Raiders are stocking up on rookie talent this offseason, and it's not just about their high-profile draft picks. While Fernando Mendoza is set to take center stage, the Silver and Black have quietly added a promising quarterback to their undrafted free agent class.

Jacob Clark, the former Missouri State signal-caller, officially signed with the Raiders on Friday. Clark put up impressive numbers in the 2025 season, completing 247 of 376 passes for 3,244 yards, 28 touchdowns, and 11 interceptions. His strong arm and accuracy could make him a sleeper to watch in training camp.

The Raiders didn't stop there. They also brought in two of Mendoza's former Indiana teammates: running back Roman Hemby and wide receiver E.J. Williams Jr. Williams made his mark with the Hoosiers last season, hauling in 36 catches for 438 yards and six touchdowns. Hemby adds depth to a backfield that's always looking for fresh legs.

But the undrafted rookie class is deep and diverse. Here's the full list of players joining the Raiders' ranks: Penn State long snapper Tyler Duzansky, BYU tackle Isaiah Jatta, Troy safety Devin Lafayette, Boise State tight end Matt Lauter, Hawaii kicker Kansei Matsuzawa, Kennesaw State cornerback Caleb Offord, Duke guard Justin Pickett, BYU wide receiver Chase Roberts, Arkansas State wide receiver Corey Rucker, N.C. State defensive end Cian Slone, UCLA defensive tackle Gary Smith III, Arkansas linebacker Xavian Sorey Jr., Maine linebacker Chris Thomas, and BYU safety Tanner Wall.

From quarterbacks to kickers, the Raiders are leaving no stone unturned as they build for the future. These undrafted gems will be fighting for roster spots come training camp, and some could surprise—just like many Raiders legends before them.
