NC and Davidson game last night

[kdays78]

Last night in the 1st half Lawson was called for his 2nd foul on NC for a push in the back I thought it was the wrong player and so did the coach so the officials had a discussion and then they changed the foul to another player. Then later on it was reviewed again and it was changed back to Lawson. Is that a reviewable call? It is not a correctable error is it? I always thought that was pretty cut and dry. It was a great game to watch as I thought overall the officials called the game tight which is the way it should be to set the tone for the season.
