The Seahawks added to their defensive line depth Tuesday, signing rookie Jordan Ferguson.
Cornerback Andrew Whitaker was waived/injured to make room on the 90-man roster, the result of a knee injury suffered in Friday's mock game.
Ferguson, who is 6-foot-1, 269 pounds, went undrafted out of Middle Tennessee State, where he was a first-team All-CUSA selection as a senior. Over his final two seasons at Middle Tennessee, Ferguson recorded 18 sacks, 34.5 tackles for loss, 126 tackles, eight passes defensed, five forced fumbles, three fumble recoveries and one interception.
After going undrafted Ferguson landed with the Memphis Showboats of the USFL, recording seven tackles and two sacks. Ferguson is the second USFL product signed by the Seahawks this summer along with rookie outside linebacker Levi Bell, who played for the Michigan Panthers before signing with Seattle.
Whitaker, an undrafted rookie out of Washington University, suffered a patellar tendon injury and will need surgery, Seahawks coach Pete Carroll said. He will revert to Seattle's injured reserve list if he clears waivers.
The Seahawks practiced at the Virginia Mason Athletic Center in Renton, Wash. on Monday, August 7 to prepare for their first game of the preseason against the Minnesota Vikings later this week.
