two foreign keys, how to map with laravel eloquent

A migration:

$table->integer('player1')->unsigned();
$table->foreign('player1')->references('id')->on('users')->onDelete('cascade');
$table->integer('player2')->unsigned();
$table->foreign('player2')->references('id')->on('users')->onDelete('cascade');

And a Model:

public function player1()
{
    $this->belongsTo('Game', 'player1');
}
public function player2()
{
    $this->belongsTo('Game', 'player2');
}

EDIT changed 'game' to 'Game' as user deczo suggested.
