Raiders defensive backs coach Marcus Robertson had a new old toy to play with Wednesday, one he had enjoyed briefly before putting it on the shelf.
Safety Nate Allen returned to practice, six weeks after injuring his right knee in the season opener. He was placed on the temporary injured reserve list, and has now started a 21-day practice window during which the Raiders must put him on the active 53-man roster or pull the plug on his season.
Allen expects to play Nov. 15 against the Vikings, the first game for which he is eligible.
