Broughton was offered a reprimand by the Match Review Panel after a collision that left Gold Coast midfielder David Swallow with an injured left ankle at Metricon Stadium last Saturday.
He elected to risk a one-week suspension by contesting the charge at the tribunal.
Broughton's legal counsel John Prior successfully argued that although Broughton slid to take possession of the ball, his eyes were on the ball at all times and the contact with Swallow occurred after he'd taken possession.
At the time of contact, Prior argued Broughton had turned his back from Swallow, who ran in from his left and into his left knee. Swallow was helped from the ground by trainers but later returned to the field.
A Gold Coast medical report tabled by the AFL's legal counsel, Andrew Tinney, on Tuesday night said Swallow would likely miss one to two weeks with a ligament strain, but the Suns have since indicated he could play in this Saturday's clash with Greater Western Sydney subject to a fitness test.
The tribunal's decision to clear Broughton of rough conduct follows its decision two weeks ago to clear North Melbourne's Lindsay Thomas of a similar charge.
In North's round four clash with the Sydney Swans at the SCG, Thomas slid into a contest feet-first and, despite beating Gary Rohan to the ball, his left leg collected Rohan, leaving the young Swan nursing a compound left tibia fracture.
AFL football operations manager Adrian Anderson issued a memo to clubs after the Thomas case seeking to clarify an earlier memo and DVD highlighting the AFL's concerns about players sliding into contests feet or knees first.
Broughton is now free to play in Fremantle's clash with Port Adelaide at Patersons Stadium this Sunday.
