PITTSBURGH (AP) The Pittsburgh Steelers bolstered their tight end depth on Tuesday, signing veteran David Johnson to a one-year deal.

The signing is a homecoming for Johnson, taken by the Steelers in the seventh round of the 2009 draft. Johnson spent five years with Pittsburgh before signing with San Diego in 2014. Used primarily as a blocker, Johnson has 24 receptions for 224 yards and a touchdown in his career.

The Steelers signed former San Diego tight end Ladarius Green in March and have Jesse James and veteran Matt Spaeth in the fold as well as they move forward without Heath Miller. The two-time Pro Bowler retired in February.
