Mitchell Johnson may have not taken many wickets in Perth Test but causes major damage by injuring Stuart Broad

For Australia, Day 3 of the third Ashes Test had many positive signs as David Warner scored a century as he continued his run march increasing to his tally as the highest run scorer in the tournament.

At the end of the day, a 350-plus lead and an injury to England's strike bowler Stuart Broad who was forced to limp to the medical facility after injuring his right foot.

The 27-year-old seamer suffered the injury when he was dismissed lbw by a full Mitchell Johnson delivery that struck him on the right foot. The injury lead to a scan and meant he missed out on the Australian second innings as he sat in the dressing room with ice and elevation as his foot was in a cast.

The other English bowlers struggled as they tried to contain the Australian batsmen, Warner in particular who always plays well in the second innings.

In his 100th Test, Michael Clarke may not be happy with his personal score but his team seems headed to another win which will secure the series for the host helping them clinch a historic Ashes win.

Johnson who has traumatised the English batsmen with his pace spells didn't get more than two wickets in the first innings of the visitors but he did great damage by injuring Broad.

With their main bowler out, things look bleak for England who are on course to lose the Ashes urn and risk a 5-0 white-wash as they look like a team at sea with bat, ball as well as in the field with sloppy performances so far.

The injury to Broad seems like another nail in the coffin of England's hopes of a win.
