Subbed on in the 66th minute in a 3-0 away win vs SudTirol. Score was the same when he came on.
Still early times, but Reggiana are equal second on the table with 7 points after 3 games.
EDIT: Gets a pass mark (6/10) and the following commentary for his half an hour performance:
Plays a good game without overdoing anything. The situation was pretty settled by the time he came on.
Also, found an interview with the coach who said Niko had received a knock which kept him out of the previous game and that he wasn't certain he would be fit to play today - good news, sounds like he's definitely in contention for a regular spot in the match day squad.
