MELBOURNE midfielder Angus Brayshaw admits he felt scared after suffering concussion twice in three weeks.

Brayshaw was first injured in the VFL against Essendon on May 1 when a football was kicked into the back of his head, knocking him out cold.

He missed a week and a fortnight later was again concussed after an incident against Sandringham.

The midfielder told SEN on Monday the seemingly innocent nature of the second concussion had him worried.

"Absolutely it does (scare me). The first knock that I got, the football was serious and obviously you'd expect to be knocked out if someone kicks a wet, muddy footy in your head, but the second one was a glancing blow," Brayshaw said.

"I was really afraid that another tiny knock could potentially set it off and once you get your third concussion in a short space of time, that's when you're looking at some real long-term consequences."

The Demons took a conservative approach with Brayshaw, and he had to deal with some worrying after-effects.

"The symptoms have been dropping off a bit, which is what you want, but I've had dizzy spells, nausea, headaches, pressure in my head, all sorts of things," he said.

"There comes a point where you rest, but there's only so much rest can do, so then they start introducing running and stuff. Thankfully I've had no real hiccups."

Brayshaw played 21 matches in his debut year after being drafted at No. 3 in the 2014 NAB AFL Draft, but has only added three games to his senior tally in 2016.

A medial strain in his left knee in the opening seconds of Melbourne's first NAB Challenge clash against Port Adelaide was another setback.
