NASCAR indefinitely suspended driver AJ Allmendinger Tuesday
evening after his sample "B" urine test came back positive for a
banned substance.  Allmendinger was suspended temporarily by
NASCAR on July 7 hours before the race at Daytona when his
sample "A" urine test from the weekend before came back positive
violating the substance-abuse policy NASCAR has in place.  Car
owner, Roger Penske, has named former Indy Car ChampionSam
Hornish Jr. driver of the No. 22 for the time being. Hornish has
been in NASCAR's Nationwide Series for the past season and a
half after a short stint in the Sprint Cup Series.  NASCAR will
not release what Allmendinger tested positive for due to its
confidentiality agreement but it is widely speculated that
something in Allmendingers diet may have caused a chemical
reaction forming the substance that is banned by NASCAR,   Now
Allmendinger has the choice to take leagal action to fight the
test or start NASCAR's Road to Recovery program. The program
takes about five months to complete
