I don't think the first team receives a penalty this week. I think there was a typo on their part due to haste
Which team will be 1st 2 the mat + will fall behind w/ a penalty?
but it could very easily be:
Which team will be 1st to the mat and who
will fall behind with a penalty
with all the shorthand in that tweet, it's obvious they wrote it quickly, and could've easily lost a word in the process
it happens to me all the time
