The San Francisco 49ers made a pair of moves on Friday afternoon in regards to their offensive tackle position. After releasing veteranJonas Jennings, the team agreed to a two-year deal with free agent Marvel Smith, in what amounts to the swapping of one injured tackle for another.
According to Matt Barrows of the Sacramento Bee, Smith's deal is filled with incentives in the event his season is cut short by injuries, which has been the case in each of the past two years.
