Braylon Edwards and state of Seattle at WR

The Seattle Seahawks have upgraded much of their roster over the past three seasons.

Wide receiver is a position still needing some attention.

That was the takeaway Sunday when the Seahawks scratched veteran Braylon Edwards from the lineup and it mattered. Edwards, named inactive with a swollen knee, had been getting additional reps in recent weeks. He even caught a touchdown pass against New England two weeks ago. But durability has been an issue for him over the past two seasons.

Edwards, 29, was expected to continue getting additional reps while Doug Baldwin misses time with a high-ankle sprain.

With Edwards and Baldwin out, Charly Martin figures to get more extensive work against Detroit on Sunday.

Sidney Rice, Golden Tate, Ben Obomanu and Martin are the four receivers active against the Lions. None has caught more than 37 passes in a season since 2010.

Rice leads the team with 22 receptions for 312 yards and two touchdowns. Tate, Obomanu and Martin have combined for 19 receptions.

Two of the veteran receivers Seattle released before the season, Terrell Owens and Mike Williams, have not signed elsewhere.
