A high school wrestler in wrestling-crazy Iowa forfeited a tournament match Thursday after refusing to grapple with a female opponent.

"As a matter of conscience and my faith, I do not believe that it is appropriate for a boy to engage a girl in this manner," Joel Northrup said in a written statement, according to the Des Moines Register.

Northrup is home-schooled but wrestles as a 112-pound sophomore for Linn-Mar High School in Marion, Iowa. He was a state title contender with a 35-4 record, CNN affiliate KCRG-TV reported.

His erstwhile opponent, Cassy Herkelman of Cedar Falls, advanced by default at Des Moines’ Wells Fargo Arena.

Herkelman (20-13), a freshman, and Ottumwa, Iowa sophomore Megan Black (25-13) are the first two girls ever to qualify for the state individual tournament, which goes back to 1926.

Black lost her opening-round match and moved to the consolation bracket. If both Northrup and Black win twice in the consolation bracket, they will be paired in the third round, forcing Northrup again to decide whether to wrestle a girl.

Northrup, the son of a minister, had indicated after the first pairings were announced Sunday that he might take the forfeit.

"My understanding is that they've got strict convictions (as a family), and I respect them," Herkelman's father, Bill, told the Register at the time. "I don't have any ill will toward them and I don't think it's any kind of boycott about her being a girl."

Northrup said as much in his statement:

"I have a tremendous amount of respect for Cassy and Megan and their accomplishments. However, wrestling is a combat sport and it can get violent at times. ... It is unfortunate that I have been placed in a situation not seen in most of the high school sports in Iowa."
