Suspended American sprinter Justin Gatlin, the 2004 Olympic 100m gold medalist and previous co-world record-holder (9.77 seconds), has appealed his four-year doping ban to the Court of Arbitration for Sport (CAS), his attorney said on Tuesday.

Gatlin, who tested positive for testosterone - or its precursors - after having submitted to a drug test at the 2006 Kansas Relays, has vigorously fought the allegations that he committed an anti-doping offense, and stated the testosterone had likely entered his body without his knowledge and without his consent.

His coach Trevor Graham has maintained that a disgruntled and bitter Nike employee rubbed a mysterious cream on Gatlin, and that triggered the positive test.

The employee, Mark Whetstine, denied those allegations.

Later, Graham speculated that he — not Gatlin — might have been the target because of anger in the track and field world surrounding his decision to send the syringe filled with steroids to USADA in 2003 sparked the fire which became the BALCO scandal. The federal investigation that Graham launched resulted in five criminal convictions and more than a dozen athlete suspensions. According to that theory, Graham's enemies wanted to take him down by implicating Gatlin, his star runner.

Logic begs to inquire that if this were really the case, that Whetstine wanted to get back at Graham, why Whetstine simply didn't plant evidence on Graham's possession, in his vehicle or at his home, call the authorities and say that he had seen Graham take with him a prohibited substance. Graham would have been implicated and no one would ever doubt again that Graham had any connection to doping athletes.

Instead, the world was spoon fed an incredulous story - which has gotten much more interesting and more detailed as time has gone along - about a pink coloured "s" swiggle, and a recollection that Gatlin told Graham to basically back off when the commotion started. You're first told by Graham that it was he who wanted to intercede, but the tube was quickly put away in Whetstine's pocket, and Graham didn't think anything more of it. Now it has changed and become more elaborate with Gatlin stating, "Let him do his job, man!"

If one takes Graham's side, Whetstine did his job so effectively that he rubbed a compound into Gatlin which had Dehydroepiandrosterone, also known as DHEA, as its active ingredient — a substance which would without question cause a positive doping test.

Something strange I would like to acknowledge here is that if Graham had any concern for Gatlin, who apparently went through every conceivable precaution as to not ever test positive (including locking his luggage, ordering room service when away), he would have stopped everything right then and there, and told Gatlin he was concerned with what had just occurred; he would have rushed Whetstine and forced his hand into the pocket. He didn't. What neatly disappeared in this version of Graham's story is the portion where Graham apparently told Whetstine that Gatlin didn't need a massage in the first place.
