Meteorite fall and the close fly-by of Asteroid DA14 - A coincidence?

Visit the following links to read reports of a meteorite fall in Russia on 15 Feb 2013, the same day that Asteroid DA14 will make a clos fly-by.  Are they connected?

The BBC report (the second link above) quotes Prof Alan Fitzsimmons, of the Astrophysics Research Centre at Queen's University Belfast, as saying that the flyby and the meteorite fall are unlikely to be connected. DA14 is expected to approach us from the South, while the meteorite that hit Russia has hit the Northern Hemisphere of the earth.

Another interesting source of information is
This one talks about the fact that an astronaut cannot be in stable orbit around the Space Shuttle – the earth will disturb his orbit and he could end up orbiting the earth instead of orbiting the shuttle. Such considerations are relevant to visualizing material loosely attached to an asteroid doing a close flyby hitting the earth’s atmosphere.
