PITTSBURGH -- The Pittsburgh Steelers have made one-year contract offers to four restricted free agents.
With the offers, the Steelers reserve the right to retain the players by matching any offers from other teams during the free-agent signing period, which starts Friday.
Essex is entering his fourth NFL season. The third-round draft pick in 2005 played in three games in 2007.
Kemoeatu is also entering his fourth season. He was a sixth-round pick in the 2005 draft and played in 15 games last season.
Warren has handled all the long-snapping duties for the Steelers since he was signed as an undrafted rookie free agent in 2005. He has played in 48 regular-season games in his three seasons with Pittsburgh.
Washington ranked fourth on the team with 29 catches for 450 yards and five touchdowns last season. He was signed by the Steelers as an undrafted rookie free agent in 2005. He has 64 catches for 1,057 yards with nine touchdowns in three seasons.
