I haven't noticed a player's position affecting his injury frequency. I believe the injury settings are static, unless you edit them; if Player X is "prone" or "durable" he's always going to be "prone" or "durable."

I don't know if the program factors in player age, either - it seems reasonable that older players would get injured somewhat more frequently than when they were younger, but I don't think 5 does this.
