Horford will come off the bench for Tuesday's preseason game against the Lakers and he will not travel to Portland for Wednesday's exhibition, Anthony Slater of ESPN.com reports.
The Warriors will go with a small-ball starting lineup Tuesday, featuring Draymond Green and Yaxel Lendeborg in the post, with Horford shifting to the second unit. It's unlikely the 40-year-old veteran will earn enough consistent minutes in Golden State this season to warrant a roster spot in most fantasy leagues.
