Before this season Allmendinger sought, and was granted his release from Richard Petty Motorsports to pursue the Penske opening. He was signed to replace Kurt Busch, but only to a one year deal. Dinger would serve as a stop gap for Penske until they could either find another driver, or Allmendinger flourished.
Unfortunately for A.J. though, this season has not gone well. His 23rd spot in the points combined with an average finish of 20.6 meant his chances of retaining the 22 seat were probably not good anyway. But now with a failed drug test on his record, there is no way Penske keeps him, barring some sort of miraculous reversal by NASCAR.
So now, with the failed test and a marginal record on track, his career options will be extremely limited. No big team or sponsor will take a chance on him, which leaves the start-and-park teams, or a move to a different (and probably lower) series.
For a guy that only a few years ago appeared to have huge potential, it really is a shame. Whether he knowingly ingested something banned or not, we are all responsible for what we put into our bodies. In any case, I hope he is able to get this worked out and get back on his feet. NASCAR Insiders
