The authors acknowledge that the following article should have been cited in our recent publication in the Journal of Athletic Training:

Impellizzeri FM, Ward P, Coutts AJ, Brown L, McCall A. Training load and injury, part 2: Questionable research practices hijack the truth and mislead well-intentioned clinicians. Journal of Orthopaedic & Sports Physical Therapy. 2020;50(10):577–584.

Information contained in our article published in the Journal of Athletic Training was intended to be complementary to, and to address the integration of, concepts introduced in our clinical commentary published in the Journal of Orthopaedic & Sports Physical Therapy. The contents of the Journal of Athletic Training article were substantively built upon some concepts initially presented in the Journal of Orthopaedic & Sports Physical Therapy clinical commentary that, regrettably, could not be explained in detail in the original publication because of word-count limitations. As the review process of the 2 manuscripts overlapped, the authors missed the opportunity to cite the first clinical commentary but acknowledge that we could have done this during the final stage of the Journal of Athletic Training review process. We acknowledge that the clinical commentary first accepted in the Journal of Orthopaedic & Sports Physical Therapy could have been cited in the Journal of Athletic Training article.

Editor's note to corrigendum:

Ethical behavior is critical to the integrity of scientific publications. Plagiarism, including self-plagiarism, is not tolerated in the Journal of Athletic Training. In this case, a concern about redundant publication was brought to our attention, and we immediately investigated this matter. When presented with this concern, the authors provided an explanation detailing the manuscript submission, review, and revision processes that led to this concern. The authors acknowledged that some contents in the 2 articles were inherently related but that the latter publication in the Journal of Athletic Training addressed this content in greater depth than their article in the Journal of Orthopaedic & Sports Physical Therapy. Having thoroughly reviewed this case, we have decided not to censure the authors because when contacted about the concern, they thoroughly explained the complementary nature of the 2 articles. We acknowledge that the article first published in the Journal of Orthopaedic & Sports Physical Therapy should have been cited in the article published in the Journal of Athletic Training.
