The San Francisco 49ers traded Daniel Kilgore to the Miami Dolphins on Thursday, clarifying exactly what Weston Richburg will be doing in Santa Clara. The move was not surprising given the Richburg addition, but it was still a quick decision.
There was a notable reason for making the decision when they did. The 49ers signed Kilgore to a contract extension in February that included $4,825,000 million fully guaranteed at signing. This included his $2,525,000 base salary for 2018, and a $2.3 million roster bonus. The roster bonus was guaranteed, but it was not due until Friday afternoon at 1 p.
