The San Diego Chargers signed former Steelers tight end David Johnson Wednesday, ending an up-and-down run with the Steelers that hit highlights of blocking excellence, and lowlights of back-to-back season-ending injuries.
Johnson was looking to fill a dual role as a tight end and a fullback in 2012 before tearing his ACL in a preseason game against the Indianapolis Colts.
He came back in 2013, the second of three previous Steelers starting tight ends to suffer injuries between 2012 and 2013, and his presence was immediately felt in terms of inline blocking.
The bug struck again, however, suffering a foot injury that cost him his 2013 season as well. Johnson's presence was missed particularly in 2013 when the Steelers' tight ends unit was among the least consistent and reliable blocking groups in the NFL. Heath Miller was coming off a torn ACL of his own and Matt Spaeth injured his foot in training camp, not having taken the field from August through November.
Johnson was a seventh-round pick out of Arkansas State in 2009.
