Gotsis, the Broncos' second-round pick in the 2016 draft, surrendered to Fulton County authorities on March 7. According to Fulton County jail records, he was released later that day after he posted a $50,000 bond. He has not yet been formally charged.
Police say the 6-foot-4, 287-pound Gotsis raped a 25-year-old woman on March 9, 2013. The woman reported last month, on Feb. 1, that she had been raped.
"We were recently informed of an investigation into an alleged incident involving Adam Gotsis that occurred in 2013 when he was in college," the Broncos said in a statement Monday. "Our organization was aware of his arrest on March 7, and it is our understanding that no determination has been made at this time as to whether any charges will be filed.
"The Broncos take an accusation of this nature very seriously and will continue to closely monitor the legal proceedings. This issue was promptly reported to the NFL as soon as we learned of it, and we will remain in communication with the league office regarding this matter."
Gotsis' attorney, Sara Becker, denied the allegations in a statement issued later Monday.
"While we were disappointed to learn of the turn the investigation was taking, we steadfastly maintain that the allegations are false," the statement read. "We will continue to advocate strongly for Adam's innocence."
Gotsis is a native of Melbourne, Australia, and came to the United States to play football at Georgia Tech. He played at the school from 2012 to 2015.
