The Seahawks signed tight end Clayton Echard, an undrafted rookie out of Missouri. Receiver Tyler Slavin was waived/injured to make room on the 90-man roster. Echard took part in Seattle's rookie minicamp as a tryout player.
Echard, who is 6-foot-4, 261 pounds, had two catches for 14 yards last season, serving primarily as a short-yardage tight end according to Missouri's website. He also spent time on the defensive line at Mizzou before settling at tight end and was a contributor on special teams. Echard will wear No. 85.
Slavin, who signed a future contract with the Seahawks in February, will revert to Seattle's injured reserve list if he clears waivers.
