Lamont Peterson has retained his status as IBF junior welterweight titleholder of the belt he won from Amir Khan in December after a review of his medical records by organization-appointed doctors ?? Peterson’s failed drug test in March.

IBF President Daryl Peoples informed RingTV.com that Peterson-Khan was examined, this after the organiztion received Peterson’s medical records for review and found that he should not be stripped.

Peterson (30-1-1, 15 knockouts) was all but stripped of the WBA’s belt, which he also took from Khan (26-3, 18 KOs), in the wake of the positive test for the banned substance testosterone that forced the cancelation of a scheduled May 19 rematch with Khan.

Peterson has been declared the WBA’s “champion in recess,” a move that appears to allow room for him to contend for that title. Khan was re-instated as the WBA’s beltholder, and Peterson named its “champion in recess,” four days prior to Khan’s fourth-round knockout loss to WBC titleholder Danny Garcia (24-0, 15 KOs) that was also for THE RING championship last month.

Peterson’s legal counsel has also asked for a postponement to August of its originally scheduled July 9 meeting with the Nevada State Athletic Commission, whose executive director, Keith Kizer, received the request from one of Peterson’s lawyers, Peter Bernard, on June 27.

Peterson and Khan contractually agreed to have their blood and urine randomly tested by the Voluntary Anti-Doping Association (VADA), whose president and founder, Margaret Goodman, informed Kizer that Peterson’s “urine specimen … was collected on March 19” and that its test results were “consistent with the administration of an anabolic steroid such as testosterone.”

In an interview with RingTV.com, Peterson said that he passed the pre-fight urine test conducted by the Washington D.C. Boxing and Wrestling Athletic Commission before facing Khan. D.C. commission director, Scottie Irving, has maintained that he has no official comment.

Peterson admitted to using testosterone in November prior to facing Khan, claiming it was for medical reasons. Peterson had a “testosterone pellet” surgically implanted into his hip by Las Vegas-based Dr. John Thompson on Nov. 12 of last year after he was diagnosed with an abnormally testosterone level.
