It hasn't been an easy autumn for Richardson, who started the year on the team's physically unable to perform list after tearing his ACL in the playoffs last January. Returning to the lineup in Week 10 against the Cardinals, Richardson hurt his hamstring after pulling down a 40-yard catch against Arizona, his only reception of the year.
"His hamstring just isn't coming back and so we're just disappointed that he wasn't able to continue to get back," coach Pete Carroll said, per the team's official website. "It just lingered a little bit. In working him out and trying to get him back, he could still feel it, so it just hasn't gone away yet like we had hoped."
