With Kenny McIntosh out of the mix, the Seattle Seahawks will experiment with a safety-turned-rusher in training camp.

The Seahawks signed running back D.K. Kaufman on Monday and placed running back Kenny McIntosh on injured reserve.

The Seahawks signed Kaufman to a contract Monday, Curtis Crabtree of Fox 13 Seattle reports.

The Seahawks have added a new running back to the roster in the wake of Kenny McIntosh's season-ending injury.

The Seahawks made a change to their interior defensive line, adding rookie Thor Griffith and waiving Justin Rogers.
