Seahawks release quarterback Jake Waters, sign receiver Deontay Greenberry

RENTON, Wash. -- The Seattle Seahawks made a roster move Wednesday morning, releasing quarterback Jake Waters and signing rookie wide receiver Deontay Greenberry.

And so Waters' time with the Seahawks ends after one uneventful week. He didn't play in the team's preseason game Friday night against Kansas City and hasn't gotten many reps during practice.

His release leaves R.J. Archer as the only healthy quarterback behind starter Russell Wilson. But it could be another indication that backup Tarvaris Jackson is on track to be ready by the time Seattle opens the regular season on Sept. 13 in St. Louis. Jackson is recovering from a high ankle sprain suffered in the first preseason game. Coach Pete Carroll said this week that Jackson is progressing well.

at 6-foot-1, 211 pounds, Greenberry went undrafted out of Houston. He finished eighth on the school's all-time receptions list and signed with Dallas, which released him last week.

Greenberry's signing comes with the Seahawks dealing with injuries at wide receiver, including one that has sidelined Chris Matthews for the past week and a half.
