Neale was offered the ban over the gut punch that floored Hawthorn's Jack Ginnivan during the Lions' nine-point win in an epic preliminary final on Saturday night.
The incident was graded intentional conduct, medium impact and body contact.
Vision shows Ginnivan wrestling with Brisbane forward Eric Hipwood, before Neale jogs over and hits the Hawthorn player with a left-handed punch to the stomach.
Adelaide forward Riley Thilthorpe and Hawks pair James Sicily and Dylan Moore have all been suspended over similar incidents this season.
Those bans came after former Lions CEO Greg Swann - in his new role as AFL football boss - brought in a minimum one-match penalty for gut punches.
New match review guidelines state intentional strikes to the stomach are automatically graded as medium impact rather than low, resulting in one-match bans.
But Brisbane are almost certain to try their luck at the tribunal as doubt over Neale's availability dominates headlines entering grand final week.
Neale has never been suspended in his 320-game career and could use the same clause that helped games record-holder Scott Pendlebury escape suspension for his bump on Adelaide's Josh Worrell this season.
Under AFL regulations, "a player with an exemplary record may argue that their good record constitutes exceptional and compelling circumstances".
Players can no longer use the so-called "good bloke" defence that helped Brisbane's Charlie Cameron overturn a ban in 2024.
Neale's other option is to attempt to have the impact grading reduced, though that route would be unlikely to be successful.
If Neale's ban stands, it would mean he not only misses the premiership decider against his former club, but could also have played his last game for the Lions.
The 33-year-old two-time flag star is widely expected to join Collingwood as a free agent in the off-season.
Neale is no stranger to grand final week drama, after his calf injury was the major talking point ahead of last year's decider against Geelong.
The brilliant midfielder ultimately played as the substitute - under a system that has since been thrown out - and starred with 17 disposals and one goal to help the Lions secure back-to-back flags.
Neale wasn't the only player under match review scrutiny after Saturday's preliminary final.
Hawthorn defenders Sicily ($10,000) and Tom Barrass ($5000) were handed massive fines for misconduct after they had angry words with umpires immediately after the final siren.
It followed a controversial finish, in which a holding-the-ball free paid against Hawthorn's Jarman Impey gifted Brisbane's Hugh McCluggage the go-ahead goal in the dying stages.
