Steelers rookie returner Kaleb Johnson made an extremely costly mistake during Pittsburgh's Week 2 matchup vs. the Seahawks. He seemed to have forgotten the NFL's new kickoff rules as he was making a play on special teams. His fingers touched the ball, and he let the ball land in the endzone, in which a Seattle player grabbed the ball and subsequently scored a touchdown.
It was an embarrassing moment for Johnson, to say the least.
