SANTA CLARA -- 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.
Washington is a 6-foot-4 receiver who ran the 40-yard dash in 4.39 seconds at Missouri's pro day. He's overcome a life of hardship, having lost both his parents by the time he was 15.
Washington had 10 touchdowns at Missouri, an alma mater he shares with the 49ers' Justin Smith, Aldon Smith and Blaine Gabbert.
The 49ers have been short on wideouts in recent days. Michael Crabtree and Brandon Lloyd battle injuries that are expected to keep them out of Thursday night's exhibition opener at Baltimore.
