Today didn't figure to end without at least one more Steelers transaction.
Brown had been noticeable on special teams the last few weeks, particularly in Pittsburgh's Week 13 romp over Kansas City. Brown was in with a few tackles in that game, and factored into one of the most dominating special teams performances in the team's recent history.
Clay, an undrafted rookie from Wisconsin, had a solid collegiate career, but left Madison early for the NFL. It appeared to be a mistake, as he was not selected in seven rounds.
He was quickly scooped up by the Steelers, a team that took undrafted free agent Willie Parker to two Pro Bowl appearances, and currently has 2nd RB Isaac Redman, undrafted as well, getting significant playing time.
It's possible Clay could be a story like that, but both Parker and Redman spent their first years after college on the practice squad, and they were both a year older than Clay. He's only up now because of Mewelde Moore's knee injury, which will keep him out of Saturday's game against St. Louis.
