Sproles had been scheduled to become an unrestricted free agent before the Chargers tagged him as their franchise player. Sproles can also take part in this weekend's mini-camp. It also means that if another team were to sign Sproles, the Chargers would receive two first-round draft choices as compensation, according to the Chargers website.
He signed the $6,621,000 contract Tuesday. His pay is the average of what the top five running backs in the league are paid. Sproles made $1.1 million in base pay last year. There is also still a chance a long term contract can be worked out.
