The Seahawks placed Eskridge (concussion) on injured reserve Thursday, John Boyle of the team's official site reports.
Since he sustained a concussion in the season opener, Eskridge has been listed as a DNP on 10 of 12 injury reports over the last four weeks. And on one of those two occasions in which he wasn't, his LP showed up on a practice estimate, meaning the Seahawks didn't even take the field that day. The team has been taking a cautious approach with what coach Pete Carroll called "a real serious concussion," and Eskridge now will have three more weeks to get through the five steps of the NFL's protocol for head injuries before being eligible to come off IR.
