The Arizona Cardinals and the San Francisco 49ers will face one another Sunday afternoon at State Farm Stadium in an important divisional matchup. The two teams face one another twice yearly and are quite familiar with one another.
They will be familiar with some players for more reasons than just facing them frequently.
Between the two teams, there are five players who used to play for the other.
The Cardinals have two former 49ers players, while the 49ers have three former Cardinals.
