Green Bay Packers inside linebacker Blake Martinez, fresh off the bye week, joined Czabe Tuesday morning as the team gets ready for its huge Sunday night showdown with the San Francisco 49ers. Martinez's right hand continues to get better and he and the team will evaluate the protection he will wear on it Sunday night. In his own words, Martinez just wants to use his right hand again. One of the biggest things Martinez and his defensive teammates will have to slow down is San Francisco's running game. They have a great backfield, led by Matt Breida who can catch and run with the best of them.
