Pound for pound, Darren Sproles was among the most dangerous weapons in the NFL. A 5-foot-6 dynamo who amassed over 19,000 all-purpose yards across his career, setting the NFL single-season all-purpose yards record with 2,696 yards in 2011. His San Diego years established him as one of football's most electrifying game-breakers, a return specialist and receiving back whose burst out of the backfield made him impossible to contain on any given play. This 2025 Panini Prizm Black Flashback Signatures card is a one-of-one, bearing Sproles' hand-signed autograph and encapsulated in an acrylic case for the highest standard of preservation. The rarest possible format for one of the Chargers' most beloved offensive weapons, this card is the definitive Sproles piece for the serious collector.
