Jim Doehring, the 1990 U.S. shotput champion who was suspended after a positive drug test, was reinstated by an arbitrator because of “procedural improprieties” at a testing laboratory, The Athletics Congress said.

Lisa Bingham of the arbitration panel said a technician at a laboratory in Indianapolis inadvertently opened a shipping container that contained a sealed sample, and that act “constituted a breach in the chain of custody.”

Doehring, 30, of Fallbrook, Calif., was suspended by TAC after testing positive for excessive amounts of the male hormone testosterone in December, 1990. The suspension was upheld by a TAC hearing panel and an appeal panel.
