Is that right way to inject data from models to another model?

Hi, Im new CI user and writing php is my hobby from some years. I want to make football manager to play with my friends. So the most important part of my code is my Match Engine, where I calculate data from my players, team tactics, reffer, weather and etc. Have 8 leagues, 16 teams every league and 8 matches per round/league every day. I make controller that is a cronjob:

Code:

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Engine extends CI_Controller {

    public function __construct() {

       parent::__construct();

       $this->load->model('League_model', 'league');

       $this->load->model('Fixture_model', 'fixture');

       $this->load->model('Team_model', 'team');

       $this->load->model('Player_model', 'player');

       $this->load->model('Reffer_model', 'reffer');

       $this->load->model('Match_model', 'match');

    }

    public function run($id) 

    {       

              //load the current league

            $league = $this->league->getLeague($id);

               //load all fixtures from this league for this round

            $fixtures = $this->fixture->getFixtures($league['id_league'], $league[$current_round]);

            foreach ($fixtures as $fixture) {

               //load reffer, home team and away team for every match

            $reffer = $this->reffer->getReffer($fixture['id_reffer']);

            $homeTeamData = $this->team->getTeam($fixture['id_homeTeam']);

            $homePlayerData = $this->player->getPlayer($homeTeamData['id']);

            $awayTeamData = $this->team->getTeam($fixture['id_awayTeam']);

            $awayPlayerData = $this->player->getPlayer($awayTeamData['id']); 

               //all data is passed to my match engine where match result is calculated

            $resultData = $this->match->start($reffer,$homeTeamData, $homePlayerData,$awayTeamData, $awayPlayerData);   

            }         

    }

}

I that the right way to load all data to my Match_model, where I have a lot of methods that calculate the match result. My first version was to load league_model, in league_model load fixture_model and etc... big nest ot claasses hard to debug.

Is there better way to do that?
