Rear Brake Caliper Scraping?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Being my usual stupid self, I dismounted the bike and didn't notice that there were smooth granite cobblestones underneath me and the cleat slipped sending me and the bike to the pavement. After this, I noticed the back break caliper on the left side (if you're looking from behind the bike) is now touching the back break rim. The back wheel isn't dead set in the centre of the caliper like the front rim.

Should this be something to worry about? Did I potentially untrue the rim? It isn't tacoed from what I can see and I used the break release and put 30km more on the bike and it seemed fine...
