Matchups command not working for NHL leagues

[DMcP89]

The $matchups command is not returning anything when using an NHL league.

[2021-11-30 23:18:44,546 INFO] [/home/dave/workspace/python/bots/harambot/harambot/cogs/yahoo.py.yahoo.standings] standings called
Error while fetching matchups for league: 70652
Traceback (most recent call last):

    team1_win_probability = "{:.0%}".format(team1[1]['win_probability'])
KeyError: 'win_probability'

Seems like the win probability will be not always get returned.
