The Steelers signed fourth-round draft pick Calvin Austin III to a four-year deal on Monday, leaving only first-round pick Kenny Pickett still unsigned.
Austin, a product of Memphis, was the second of two wide receivers the Steelers selected in the draft last month. The team also took George Pickens in the second round.
The speedy Austin caught 156 passes for 2,541 yards and 22 touchdowns after earning a spot on the Memphis roster as a walk on.
He also is an excellent returner, averaging 11.1 yards on 29 career punt returns with two touchdowns.
Austin and the rest of the Steelers rookie class -- including Pickett -- will be on hand Tuesday as the team holds its mandatory minicamp at the UPMC-Rooney Sports Complex.
