The Raiders have designated cornerback Antonio Hamilton to return from injured reserve, as Scott Bair of NBC Sports Bay Area tweets. The move will trigger a three-week window for Hamilton to return to the 53-man roster. If he is not activated within that timeframe, he will not be eligible to play for the remainder of the season. 
The move officially means that will will not see kicker Sebastian Janikowski or offensive lineman Denver Kirkland take the field again in 2017. Each team has only two IR-DTR spots to use and one has already been burned to activate safety Obi Melifonwu.
Hamilton underwent arthroscopic surgery to repair a torn meniscus back in October. Before that, the second-year player appeared in four games, primarily as a special-teamer. Last year, he made ten appearances. Per league rules, Hamilton will be eligible to play against the Cowboys on Dec. 17.
