In advance of the Tuesday start of the NFL’s free agency period, the Seahawks Friday made four roster moves. They terminated the contract of veteran TE Zach Miller, waived OT Garrett Scott and DT Jesse Williams, and signed defensive end Greg Scruggs to a one-year deal.

The jettisoning of Miller came as no surprise. Miller signed with Seattle in 2011 after four seasons with the Oakland Raiders and played in 48 games with 46 starts, recording 102 receptions for 1,092 yards and eight touchdowns. He was a key player in the team’s 2013 season that culminated in the Super Bowl triumph.

His 2014 season was cut short after three games and six catches for 76 yards due to an ankle injury, which required two surgeries. He ended the season on injured reserve. Miller is 29.

Scruggs was selected in the seventh round (232^nd overall) of the 2012 draft. He spent 2013 on injured reserve and played in three games last season before landing on injured reserve. In three seasons, he has played in 15 games with eight tackles (six solo) and two sacks.

The Seahawks drafted Scott out of Marshall in the sixth round in 2014. He signed a rookie contract May 14 that year but was released the next day due to a rare heart condition. The Seahawks paid his $100,000 signing bonus.

Williams, an Australian who was an all-SEC player at Alabama, was a fifth-round draft choice in 2011. He spent the past two seasons on injured reserve with knee problems.
