Warner temporarily out of action after being hit at nets

Australia's torrid relationship with the Melbourne Cricket Ground (MCG) nets this week continued with explosive opener David Warner hit on the right forearm Saturday morning.

The opener, who was struck a nasty blow on his left thumb at the Gabba last week, was hit by a Peter Siddle delivery during a net session before play on day two of the ongoing second Test against India.

In exclusive footage of the incident captured by cricket.com.au's daily live stream of the morning net sessions, Warner turned his head as the ball headed towards him and glanced off his unprotected forearm.

He threw the ball back to Siddle before immediately leaving the nets and heading to the rooms.

The full extent of Warner's injury is yet to be determined, but it was serious enough to prevent him from taking the field Saturday.

"David Warner was hit in the right forearm during this morning's net session," a Cricket Australia spokesperson said.

"He has significant bruising which is limiting his ability to field at the moment."

Warner is the fourth Aussie player to be injured at the MCG nets this week.

Shane Watson and Mitchell Starc both left training early after being struck in the nets Tuesday; Watson was hit on the helmet, while Starc edged a ball onto the inside of his knee.

The following morning, Shaun Marsh was struck on the left thumb and required treatment before he continued his session.

None of the injuries were serious; Watson and Marsh both took their place in Australia's eleven for the Boxing Day Test, while Starc was named 12th man.

It is yet to be confirmed whether or not Warner will bat again in this match and he will be hoping to be fit for the fourth Test in Sydney starting Jan 6.

All-rounder Mitchell Marsh has already been ruled out of the SCG clash after suffering a setback in his rehabilitation from a slight hamstring strain.
