MIAMI -- Pat Riley is back on the scouting trail.
Assistant coach Ron Rothstein filled in when Riley missed a game against Orlando last week while on another scouting trip. Rothstein was handling the game-day coaching responsibilities on Friday, and was expected to stay in that role Saturday when the Heat visit Charlotte.
The Heat (12-55) have struggled with injuries this season. Star Dwyane Wade ended his season early because of a long-troublesome left knee.
