EmberJS filter hasMany data, apply to belongsTo relationship

I have this teams model:

export default DS.Model.extend({
    "name": attr('string'),
    "players": DS.hasMany('player',{
        async: true
    })
});

along with this player model:

export default DS.Model.extend({
    "name":  attr('string'),
    "status": attr('string'),
    "team": DS.belongsTo('team',{
        async: true
    })
});

If I want to list out all the teams, easy enough. And if I want to list out all the teams, and within each team, list out all the players... also simple enough.

{{#each teams as |team index|}}
    <strong>{{team.name}}</strong></br>
    <em>Players</em>
    <ul>
    {{#each team.players as |player|}}
        <li>{{player.name}} - {{player.status}}</li>
    {{/each}}
    </ul>
{{/each}}

My QUESTION... let us say certain players are injured. If I'm looping through the teams, how would I go about ONLY displaying Teams that have injured players. If at least one player is injured, the TEAM will display, if not... the team will not display?

You can try filtering using isAny method for players

export default Ember.Route.extend({
    model() {
        return this.store.findAll('team').then((teams)=>{
            return teams.get('players').then((players) => {
                return players.isAny('status','injured');
            })
        })
    }
})
