Seattle Seahawks middle linebacker Lofa Tatupu has not passed his post-concussions tests and will be a game-time decision on Sunday, head coach Pete Carroll said on 97.3 KIRO radio in Seattle, via Liz Mathews of 710 ESPN Seattle.

Tatupu suffered a concussion during a collision with New Orleans Saints running back Julius Jones during the fourth-quarter of the Seahawks' 41-36 win on Saturday.

A three-time Pro Bowl middle linebacker, Tatupu finished second on the team in tackles (89) and was tied for the team lead in passes defensed (8) this season.

If Tatupu is unable to play, linebacker David Hawthorne, who led the team in tackles for a second straight season, would move to the middle in base defense, with nickel linebacker Will Herring taking Hawthorne's spot on the weak-side.
