A high-speed chase through the Cape Flats ended in a gunfight after a car rammed pursuing traffic co.
Premier Soccer League officials say that though they are not yet pursuing a ban, it has become a topic of conversation after a rise in incidents where the vuvuzela was used to cause harm.
"Our rules ban all dangerous weapons from matches," PSL general manager Derek Blanckensee said.
"If the vuvuzela is to become a dangerous weapon then we will look into this."
Vuvuzelas were among a number of objects thrown at Orlando Pirates coach Roger de Sa after his side were held to a draw by AmaZulu at the Moses Mabhida Stadium last week.
On Saturday, a supporter, angry at a red-card decision against his team, charged on the pitch and attempted to strike the referee with the plastic instrument during a league match between Lamontville Golden Arrows and Kaizer Chiefs in Durban.
A second Chiefs fan was stopped after he too went on the pitch. Both were arrested and released on R500 bail earlier this week. The incidents have not only called into question security at PSL games but also the future of the vuvuzela.
