Coach Pete Carroll acknowledged Friday that the Seahawks may place Carson (neck) on injured reserve, with the running back now ruled out for a second straight game, Michael-Shawn Dugar of The Athletic reports.

Carroll suggested it was a discussion rather than a decision, whereas for QB Russell Wilson (finger) it's a matter of when, not if, he'll be placed on IR. The coach was optimistic about Carson at the beginning of the week, but the running back is now set to miss a second straight game and likely more. Alex Collins figures to be the lead runner Sunday night in Pittsburgh, backed up by DeeJay Dallas and Travis Homer.
