Seahawks tight end Anthony McCoy, waived-injured on Tuesday, went unclaimed by another club and reverted to Seattle’s injured reserve list Wednesday.
McCoy, 25, suffered an Achilles tear last week. He caught 18 passes for 291 yards and three touchdowns for Seattle in 2012.
In separate roster moves, the Seahawks waived rookie wide receiver Matt Austin (left squad) and offensive guard Jordan Roussos. Both were undrafted free agents who signed with Seattle after the draft.
Taking their spots in Seattle were two other undrafted free agents: wide receiver Greg Herd and defensive tackle Michael Brooks.
The Seahawks were awarded Brooks, who played collegiately at East Carolina, on waivers from Detroit. Herd, formerly of Eastern Washington, was waived by Dallas on May 13.
The Seahawks’ moves were disclosed in the NFL’s Wednesday transactions.
