The San Francisco 49ers beat the division rival Arizona Cardinals on Monday evening. However, they lost starting RB Frank Gore (broken right hip) in the process.

The team placed Gore and backup WR Dominique Zeigler (left ACL tear) on injured reserve. To fill their spots on the 53-man roster, the 49ers have signed S Chris Maragos and RB DeShawn Wynn from the practice squad.

“It is unfortunate that we had to place Frank on IR,” said head coach Mike Singletary. “He is not only a great football player, but a tremendous leader. He plays with such passion and desire, two traits that will serve him well as he recovers from the injury.”

With Gore gone for the rest of the season, the team will turn to veteran RB Brian Westbrook to be the main ball carrier the rest of the way. However, the coaches must be careful to not overwork the veteran back since he’s had major knee problems over his career. It will help that Westbrook will get to play all but one of the team’s final five games natural grass.

Additionally, the team has waived K Shane Andrus and has released OT Xavier Fulton from the practice squad.

The release of Andrus is a clear signal that K Joe Nedney (knee), who missed the past two games, will be able to play against the host Green Bay Packers this Sunday.
