Doug Baldwin out for Sunday's game at Detroit
"Unfortunately, he's going to be a couple weeks anyway," coach Pete Carroll said.
That's a setback for Seattle's offense, which had worked to reincorporate Baldwin, the team's top receiver a year ago.
In his first three games this season, he caught four passes for a total of 23 yards. In the last three games, he caught seven for 126 before suffering the ankle injury on a special-teams play in the first half.
Carroll said the Seahawks will turn to Charly Martin as the slot receiver as well as using Golden Tate in that role. Tate started at split end the first seven games this season, but Carroll indicated that spot remains subject to competition with Braylon Edwards.
But the loss of Baldwin is a significant setback. "We were just getting him going," Carroll said. "We felt like he was coming around."
Baldwin has struggled with injuries that go back to the offseason. He had a sore hamstring that he had drained of blood in August, he suffered a dental injury in Week 1 when his front two teeth were broken in a diving attempt at a touchdown catch in Arizona. He missed Seattle's third game with a sore shoulder, which he suffered in practice, and now it's an ankle injury.
"He hasn't been healthy, really," Carroll said. "I think it's just a matter of he's just not had any continuity at all to this offseason."
