Jeneba Tarmoh, the 22-year-old sprinter who ran to a dead heat with training partner Allyson Felix for third place in the 100m at the Olympic Trials, is backing out of the run-off she originally agreed to and is conceding her place on the Olympic team to Felix.

According to a statement released by USA Track & Field, Tarmoh's agent Kimberly Holland sent an e-mail to USATF president Stephanie Hightower at 9:37 a.m. PT that confirmed Tarmoh's withdrawal from the tie-breaking procedure.

The e-mail read, "I Jeneba Tarmoh have decided to decline my 3rd place position in the 100m dash to Allyson Felix. I understand that with this decision I am no longer running the 100m dash in the Olympic Games and will be an alternate for the event. As an alternate I understand that I will be asked to run if another 100m runner decides not to for personal reasons, and/or on the 4x100m relay."

Hightower said in the statement: "We are disappointed that Jeneba has changed her mind regarding her position on the Olympic Team. We all worked hard to reach a consensus on the tiebreaker, but we know that Allyson, Carmelita (Jeter) and Tianna (Bartoletta) will represent Team USA well."

In a statement released through her publicist, Felix said, "The situation has been difficult for everyone involved. I had accepted the USATF decision and was prepared to run at 5pm. I wanted to earn my spot on this team and not have it conceded to me so I share in everyone’s disappointment that this run-off will not happen. All I can do now is turn my focus to London."
