The trial of Jurrah has entered its third day at the Alice Springs Supreme Court with evidence from Bruno Wilson, who was with a group that included Jurrah at the Little Sisters town camp on March 7 last year.
Jurrah seen with weapon: court told
The former footballer has pleaded not guilty to the charge of seriously injuring his cousin Basil Jurrah, and if convicted could face up to 14 years in prison.
Mr Wilson said Liam Jurrah was not armed when they ran into Little Sisters.

He said he could see Basil Jurrah, who was with a rival group, holding a nulla nulla - a type of traditional Aboriginal club - and a machete.
After the group he was with caught up with the alleged victim, Mr Wilson said one man smashed out Basil Jurrah's front teeth using the blunt end of an axe.
Mr Wilson said he then tried to stop the group from further hurting Basil Jurrah, but he did not see Liam Jurrah taking part in the attack.
"He was at the group standing," Mr Wilson said.
Earlier in the trial, the court was told there were two violent incidents at Little Sisters on the night in question.
Liam Jurrah was allegedly involved in both incidents.
Basil Jurrah is listed to give evidence later in the day.
Outside court on Wednesday, two men were involved in a fist fight during a break in proceedings.
The trial continues.
