"Lions wide receiver Calvin Johnson will return today against the Seahawks after missing two games with a right knee injury. Running back Kevin Smith will play after leaving the last game with a shoulder injury.

But defensive tackle Grady Jackson will be inactive. A Lions spokesman said it was the coaches' decision. Jackson, a 36-year-old veteran who had off-season knee surgery, was listed as probable on the injury report Friday. The Lions signed defensive tackle Joe Cohen off the practice squad Saturday, and Landon Cohen will start in Jackson's place."
