Defensive backs coach Curtis Fuller of the Carolina Panthers resigned this week following an investigation into complaints of inappropriate conduct, the team announced on Friday.
The Charlotte Observer reported that Fuller, 39, who joined the Panthers as a coaching assistant in 2013, sent inappropriate texts and emails to an unknown number of female staff members.
"After approaching Coach Fuller with the findings of an investigation into complaints of inappropriate conduct, we accepted his resignation," Panthers spokesperson Steven Drummond said in a statement to NFL.com. "The Panthers are deeply committed to ensuring a safe, comfortable and diverse work environment where all individuals, regardless of sex, race, color, religion, gender, or sexual identity or orientation, are treated fairly and equally."
A source told the Observer that the volume of communications, rather than their content, was the primary issue.
Fuller was a fourth-round draft pick of the Seattle Seahawks out of TCU in 2001 and played safety for parts of three seasons with the Seahawks, Green Bay Packers and Panthers, and had previous coaching experience with the Packers, Oakland Raiders and Tennessee Titans.
Panthers majority owner Jerry Richardson announced he was selling the team in December after the league took over an investigation looking into allegations of workplace misconduct against him.
Richardson, 81, remains under NFL investigation.
