The Cowboys are looking for some speed on special teams and possibly on offense. The team is hoping rookie Lance Dunbar can help in both areas. The Cowboys signed Dunbar (5-8, 191) from the practice squad to the 53-man roster on Monday. Taking his place on the practice squad will be wide receiver Raymond Radway, who has been with the Cowboys the last two training camps and spent all of 2011 on injured reserve with a broken leg. Radway, who was released back in August before the final preseason game, worked out for the Cowboys on Friday at Valley Ranch.
