Here's a tweet from Lance Gross sent last night. However, no word on what his character entails.
"Chillin on set. Shooting "The Finder" on FOX this week and next week. 1st day of 8!"

The New FOX Series The Finder, set to premiere midseason 2012 on Thursdays at 9pm, is based on Richard Greener's The Locator book series and stars Geoff Stults in the lead role. Michael Clarke Duncan will portray Leo Knox, the legal advisor, bodyguard, and best friend to the lead character.

Created and written by Hart Hanson and directed by Dan Sackheim, The Finder centers around Iraq war veteran Walter Sherman, who is discharged after suffering brain damage from an explosion, discovers he has a "unique gift to help others recover what they've lost."
