Evans is the latest AFL player facing suspension for homophobic language after an incident involving the 18-year-old during last Saturday's VFL game against Coburg.
It comes less than a fortnight after the league sacked its appeals board chairman Will Houghton, in the aftermath of St Kilda player Lance Collard's ban for calling a VFL opponent a "f***ing f****t" last month.
Houghton was axed after saying racist, sexist or homophobic language was "commonplace" in the AFL when adjudicating St Kilda's appeal.
Saints forward Collard has served a two-week ban after being found guilty of using homophobic language, after initially being banned for seven weeks.
Brisbane said Evans, drafted last year with pick No.38, was remorseful.
"The club is aware of the incident and has been working with Coburg and the AFL on it," the Lions said in a statement.
"The club has confirmed the player has apologised multiple times - on-field and again post-match.
"The player is extremely remorseful and takes full responsibility.
"The club is disappointed the incident has occurred, while supporting and educating the player."
Evans has yet to make his AFL debut.
Collard's latest suspension came less than two years after a six-game ban for the same offence.
Adelaide's Izak Rankine was banned for four matches last year for the same offence, missing the Crows' finals series.
Untried Sydney defender Riak Andrew (five matches) and West Coast player Jack Graham (four) were also suspended last season.
In 2024, now-retired Port Adelaide player Jeremy Finlayson was handed a three-match ban and Gold Coast midfielder Wil Powell was suspended for five matches.
AFL boss Andrew Dillon had condemned the reduction of Collard's penalty after Houghton was sacked.
"Let's be clear: homophobia has no place in Australian football. Not at any level. Not under any circumstances," Dillon said in a statement on Friday.
"We will not accept, excuse or normalise behaviour and language that demeans, discriminates or vilifies people based on who they are."
