Atlanta Hawks 的三年生大前鋒John Collins 被驗出對某種NBA禁藥有陽性反應 (Growth Hormone Releasing Peptide-2，刺激生長激素分泌的藥品)，違反了NBA 的Anti-Drug 規例，將面臨25場無薪禁賽。Collins 表示計劃對停賽期作出上訴。
22歲的Collins 是Hawks 第一籃板搶奪點、第二得分點，他今季暫時爲止場均17.0分、8.8籃板。
Collins 是今個球季第三位球員被判罰25場停賽，第一位是Brooklyn Nets 的Wilson Chandler (Ipamorelin，生長激素刺激劑)，第二位是Phoenix Suns 的Deandre Ayton (利尿劑)。
以下是John Collins 的聲明：
“First I want to apologize to my teammates, the Hawks organization, our fans, partners and community as a whole for this situation. I understand the impact this matter has on what we are trying to achieve together this season, and I am incredibly frustrated and disappointed in myself for putting all of us in this position. I have always been incredibly careful about what I put in my body, but I took a supplement which, unbeknownst to me, had been contaminated with an illegal component. I plan to appeal my suspension in arbitration so I can get back on the court as soon as possible and continue to contribute to our 2019-20 campaign.”
