Mike Brown said he will not hold back despite his concussion

England full-back Mike Brown will not hold back in tackles against Scotland despite his recent concussion troubles.

Brown was knocked unconscious during an accidental collision with Italy's Andrea Masi a month ago and was forced to miss the Six Nations defeat in Ireland.

Now fully fit and restored to the starting XV for Saturday’s Calcutta Cup clash with Scotland, Brown said he will not be at all wary when challenging for the next 50-50 ball.

The 29-year-old said: "It hasn't been like that in training so far, although obviously that is a bit different to being in a game.

"The way I play, I can't afford to do that because it would take so much away from my game.

“I think I'm 100 per cent committed every time I'm going for a ball.

"Hopefully I will just switch into automatic mode and won't think too much of it. We'll see when I get out there."

Frustrating

Brown added he was annoyed with himself after the accident which saw him rolled on to a spinal board and regain consciousness in the changing room.

The England star got an ovation from the Twickenham crowd when he emerged to watch the second half from the stands.

He said: "I was just thinking: 'why didn't I get my head in the right position or get there quicker so I didn't have to make the tackle?' It's just annoying.

"I only managed 12 minutes of the game which is even more frustrating because I didn't do anything in the game to be happy about.

“I got knocked out and that was it.

"I was a bit embarrassed by the applause when I came out. I only lasted 12 minutes and I didn't do much in those 12 minutes to warrant that applause.”
