The 49ers have struck a deal with veteran cornerback Nnamdi Asomugha, a league source confirmed this afternoon. Asomugha, who played at Cal, who had his best NFL seasons while with the Raiders and who makes his offseason home in the Bay Area, will sign a one-year deal with the 49ers. He will have the most recognizable name of any of the 49ers' cornerbacks in 2013. However, his spot on the roster, and certainly the starting lineup, is not guaranteed. The one-year deal is worth $1.35 million in base salary with no guaranteed money, meaning the 49ers could cut him with no future entanglements if they so desired. The deal is worth as much as $3 million if Asomugha meets specific incentives. The 49ers had a little more than $3 million in salary-cap space before Asomugha's signing.
