Two days after the Pittsburgh Steelers lost to the Los Angeles Chargers in 2018, the team signed Ralph Webb to their practice squad. Most fans did not notice the move as they were roiling over the tough loss which featured some questionable calls. With starting running back James Conner injured, the team made the move for deep insurance when they promoted Trey Edmunds. That is where Webb remained for the final month of the season.
Webb must have made enough of an impression that after the season they signed him to a reserve/future contract in January.
