Seattle Seahawks middle linebacker Lofa Tatupu has passed his post-concussion tests and is expected to play today, Jason La Canfora of the NFL Network reports.

Tatupu was concussed during the fourth-quarter of the Seahawks' 41-36 win over the New Orleans Saints last Saturday. The three-time Pro Bowler was held out of practice on Wednesday and Thursday, but participated in Friday's non-contact walk-through before the team departed for Chicago.

As Seattle's signal-caller, Tatupu is the veteran quarterback on defense, playing in all of the team's defensive packages. Tatupu finished the season with 89 tackles, 1 quarterback sack, and 1 interception, which he returned for a touchdown.

If Tatupu is limited, Seahawks leading tackler David Hawthorne would play middle linebacker, with Will Herring stepping in for Hawthorne at weak-side linebacker.
