What's Kerry Wood's playoff role?

With the playoff's starting, the bullpen roles probably change with more days off... Marmol and Howry are probably the primary set-up men for the majority of games instead of every other game..

Could Lou used Wood as the long reliever?  Perhaps bring him in in the 4th or 5th inning, if a starter is really struggling and pitch him for 2 or 3 innings?  I know Wood hasn't pitched more than 2 innings yet.  But he's been good in his last 2 inning outings and perhaps we see Lou extend him for 3 innings in the next day or two??  

I have a feeling that Lou will have a much quicker hook in the playoffs, since the pen's been very strong of late.
