The Seahawks have signed outside linebacker Mister Alexander. It was first reported Aaron Wilson, but confirmed by the Everett Herald's John Boyle.
Alexander, 6'3, 252, was signed by the Texans as a UDFA in 2011 out of Florida State, and appeared in 12 games for Houston, mostly on special teams. He spent time with the Toronto Argonauts in 2013, was released, then played with the Omaha Mammoths of the Fall Experimental Football League in 2014 before catching on with the Cowboys' practice squad.
As Zach Whitman's SPARQ database tells us, Alexander comps, athletically, to Georgia's Alec Ogletree. He is likely a hedge for Malcolm Smith leaving in free agency, and he'll compete with any other free agent signing at outside linebacker and/or any draft pick coming in next season.
The Seahawks now have ten linebackers on their roster, as Alexander joins K.J. Wright, Bobby Wagner, Bruce Irvin, Kevin Pierre-Louis, Malcolm Smith, Brock Coyle, Mike Morgan, Mike Taylor, and Brendan Kelly. Smith is a soon-to-be unrestricted free agent and Morgan will be a restricted free agent.
