WATCH: Cards' Carson Palmer spikes ball, self

Posted at 5:03 PM, Nov 30, 2015

Arizona Cardinals quarterback Carson Palmer is mild-mannered off the field but as an intense a competitor as you'll find during games.

Case in point: After he scored on a game-winning 8-yard touchdown in the fourth quarter of the Cards' 19-13 win at the San Francisco 49ers -- by far the longest TD run of his 13-year pro career -- he aggressively spiked the football in celebration.

The only problem was it was a bit too aggressive, as he took himself down along with the football.

Cardinals fans collectively held their breath for the several seconds it took Palmer to get back up. Fortunately, the veteran QB and regular-season MVP candidate was OK. 

Nice run, Carson! Please don't ever do it again.
