Steelers reach play-offs but Dontari Poe adds insult to injury for Broncos

The Pittsburgh Steelers clinched their NFL play-off place with a last-gasp win over the Baltimore Ravens - but reigning champions the Denver Broncos were dumped out and embarrassed by the Kansas City Chiefs.

Antonio Brown's touchdown with nine seconds remaining earned the Steelers a 31-27 win and with it the AFC North title as they rallied from 17-10 down to eliminate their fierce rivals from play-off contention.
