Seahawks fill spots with three signings as Bud Clark, Mason Richman go IR

The Seahawks reshaped their 90-man roster ahead of Friday’s preseason finale by placing Bud Clark on injured reserve with a broken ankle and Mason Richman on IR for the season, then filling the openings with three free agents: RB Justin Jones (returning after a Cowboys game), safety Derrick Johnson (Tysheem Johnson) and offensive tackle Derrick Graham (the son of a former Seahawk), as Amari Kight is out and Rodney Thomas II is recovering from hand surgery; the moves come as Seattle prepares for the Chiefs game and look to shore up depth.
