Horford will come off the bench for Friday's preseason opener against Denver, Justin Turpin of WEEI.com reports.
Luke Kornet will get the start for the first preseason matchup, and Horford is expected to receive minutes off the bench. With Kristaps Porzingis (foot) expected to miss at least the first month of the season, preseason will likely show who replaces him in the starting lineup to begin the year -- though Horford is still the favorite to step into the starting five.
