I have an object which needs a dependency injected into it

public class FootballLadder
{
    public FootballLadder(IMatchRepository matchRepository, int round)
    {
        // set initial state
        this.matchRepo = matchRepository;
        this.round = round;
    }

    public IEnumerable<LadderEntry> GetLadderEntries()
    {
        // calculate the ladder based on matches retrieved from the match repository
        // return the calculated ladder
    }

    private IMatchRepository matchRepo;
    private int round;
}

For arguments sake, lets assume that I can't pass the round parameter into the GetLadderEntries call itself.

Using StructureMap, how can I inject the dependency on the IMatchRepository and set the initial state? Or is this one of those cases where struggling against the framework is a sign the code should be refactored?
