The 49ers claimed rookie wideout L'Damian Washington off waivers Sunday from the Dallas Cowboys, who happen to be their season-opening opponent in exactly five weeks.
Washington, an undrafted rookie out of Missouri, fills a roster spot created by the corresponding release of wideout Jon Baldwin. The 49ers got Baldwin last Aug. 19 from the Kansas City Chiefs for A.J. Jenkins, in a swap of first-round busts; Baldwin was a 2011 top pick and Jenkins the 49ers' No. 1 choice in 2012.
