The San Francisco 49ers lost special teams standout Demarcus Dobbs for the rest of the season as a knee injury suffered against the Miami Dolphins on Sunday landed him on injured reserve.

With Dobbs being placed on injured reserve, the 49ers had two open roster spots after suspending running back Brandon Jacobs for the final three games of the regular season on Monday.

According to Matt Barrows of the Sacramento Bee, the 49ers wanted to sign linebacker Matt McCoy to fill Dobbs role on special teams. However, McCoy failed his physical with the team. McCoy suffered a season-ending knee injury while with the Seattle Seahawks in 2011.
