Coach Mike Tomlin continues to work on filling out his new staff with the Steelers, promoting Ray Horton to secondary coach and hiring a special teams coach.

Horton, according to a Steelers source, will coach the secondary by himself. He was the assistant secondary coach the past three seasons to Darren Perry, who resigned his position after Tomlin was named to succeed Bill Cowher.

Pittsburgh native Bob Ligashesky, 44, will become the Steelers' new special teams coach, according to a report in the St. Louis Post-Dispatch. Ligashesky, a 1985 IUP graduate, was the Rams' special teams coach the past two seasons. He also was Pitt's tight ends coach and special teams coordinator from 2000-03. He played linebacker at IUP.

Ligashesky coached at Kent State, Bowling Green and one year as assistant special teams coach with the Jacksonville Jaguars in 2004. He was a graduate assistant coach at Wake Forest and Arizona State.

According to a Steelers source, the team will hire an assistant special teams coach as well. Kevin Spencer, who coached the Steelers special teams from 2002 through last season, was permitted to join Ken Whisenhunt's new staff with the Arizona Cardinals.

Horton, 46, coached with the Redskins, Bengals and Lions in the NFL before joining the Steelers in 2004. He played cornerback for the Bengals from 1983-88 and finished his career with the Dallas Cowboys from 1989-92.
