Some nighttime sports shots

How do you guys who shoot sports at night handle the conditions? It seems that either I get quite a lot of grain, or if I attack the photo with noise ninja, it ends up looking artificial (example here).
These ones were shot during the reserves game, at ISO 1100, 1/400, f/2.8

I consciously decided that I would not use any noise reduction OR sharpening, just levels and WB, so that I wouldn't end up with the fake plastic look that over-use of NR gives you. What do you all think - acceptable or not? I guess they are not really portfolio quality, but I've seen worse on the back page of papers
