With the Steelers punching their ticket to the postseason on Sunday afternoon, Steelers Nation was buzzing with excitement. For Steelers Nation Unite members, Sunday came with added benefits.

With the Heinz Field crowd ready to witness the Steelers extend their season, Steelers Nation Unite members who RSVP'd and Checked In on Sunday were invited down to the sidelines for a number of exclusive pregame experiences.

Following warmups, members assisted in unfurling the Terrible Towel on the field. When the unfurl finished, Steelers Nation Unite members lined the Heinz Field turf as the team ran out of the tunnel for pregame introductions. Finally, with kickoff only a few moments away, members helped lead the Terrible Towel twirl in the stadium.

Once the game began, members began receiving surprises at their seats, including Steelers gift cards and Steelers Nation Unite gear.

Steelers Nation Unite presented a one-of-a-kind surprise to member Darrin Stack, as the team's all-time sacks leader Jason Gildon delivered a signed jersey to Stack at his seat during the first quarter, which was also shown on the scoreboard.

Following the game, a group of members who checked in during the game on Sunday were invited down to the field for photo opportunities.

Members not at the game are also getting rewarded this week. Using #SNUCheckIn, members shared photos of where they cheer on the team each week and will be receiving prizes for participating.

Fans will not want to miss out on opportunities that are coming this week, both for members at Heinz Field and members watching from home, as the Steelers are recognizing all of Steelers Nation for their dedication with a "Thank You Fans" game on Sunday night.
