Love this coverage - Not!

Ok, I can see after 93 laps covered so far that this half of the season may leave some people perplexed about what happened to their driver, that is if their driver isn't one of the top names in the sport.

Case and point - Jamie McMurray.  No, he wasn't running well, in fact he was running back in the 30's as far as position, but I noticed the scroll across the top of the screen (and on Nascar online) that all of the sudden he was in 43rd.  What happened?  No one has made mention of it, he's back up to 33rd now (a lap down), but no mention of what happened, if they had a problem and had to pit, no nothing.  Anyone know what happened?

Other than that it seems like a typical follow the leader race so far, one caution for debris and I expect the field to spread out again until another caution comes out.
