Marcus Smart is aiming for a return to the Boston Celtics' lineup for Game 2, sources tell Chris Haynes of Yahoo! Sports.

Smart's availability depends on how his foot sprain responds to treatment over the next 36 hours.

The Celtics increased the minutes for Derrick White, Payton Pritchard and even played Aaron Nesmith to fill in for Smart. 

The Celtics trail the Miami Heat 1-0 in the Eastern Conference Finals.
