San Francisco 49ers running back Reggie Bush is reportedly planning on suing the city of St. Louis after suffering a season-ending knee injury after slipping on concrete at Edward Jones Stadium, according to Jason La Canfora of CBS Sports.

Bush reportedly will have Shawn Holley and her KWIKA firm handle his case, which will plan to aim the suit at the Stadium, which is owned and operated by the city of St. Louis, according to La Canfora. The 49ers running back has been placed on injured reserve after tearing his MCL.

Bush was only under a one-year contract with the 49ers and is an unrestricted free agent after the season. The problem for Bush is that teams may look at the explosive running back and choose not to take a chance on him because of his history with injuries. Bush has only completed a full 16-game season twice in his NFL career, and an injury this significant could impact his future in the league.

The NFLPA has reportedly contacted the NFL about the concrete issue at the stadium, according to La Canfora. The Rams have worked to fix the issue at the stadium, but that comes after Bush's season-ending injury. Bush's legal team will reportedly seek gross negligence, as there was potential danger in having the concrete surface so close to the playing field, according to La Canfora.

The 49ers have been at the front of headlines. Whether it's quarterback Colin Kaepernick playing his last season in San Francisco, or Reggie Bush suing the city of St. Louis, it has been a difficult season for the 49ers.
