Polls are open for the semifinal matchups of the Helmet Madness bracket challenge.
Voting in each matchup will take place over two days on the website and votes can be cast every 30 minutes. Voting is logged per IP address, which means if you have multiple devices on one Wi-Fi network, only one device may vote per 30 minutes on that network.
Voting in these matchups runs until noon on Thursday, March 18.
