Pittsburgh signed Smith in January to a reserve/futures contract. The move leaves veteran Charlie Batch as the team's most likely backup quarterback with training camp fast approaching. In addition to starter Ben Roethlisberger, the team has former Texas A&M quarterback Jerrod Johnson on their roster.
Smith was a fifth-round pick by the Baltimore Ravens in the 2007 NFL Draft. The 49ers added him to their roster in 2010, and he started six games that season. He was let go prior to the start of the 2011 season, where he latched on in the UFL.
