Australia opener Cameron Bancroft was dropped for Marcus Harris at Headingley while Jason Roy was declared fit for an unchanged England, who opted to field first in the third Ashes Test.

Tim Paine's team, 1-0 up in the five-match series after their victory at Edgbaston was followed by a drawn Test at Lord's, made three changes to their XI.

One was enforced as Steve Smith was ruled out on Tuesday following a bout of concussion, and Marnus Labuschagne, his replacement during the game at Lord's, came into the team from the start in Leeds.

The tourists also chose to replace opener Bancroft with Harris and bring in seamer James Pattinson – who featured at Edgbaston – for Peter Siddle.

England had concerns over Roy's availability after he suffered a blow to the helmet in the nets on Tuesday, but he was declared fine to feature following concussion tests.

The toss was put back by 40 minutes due to drizzle on a dull morning and though play was due to commence at 11:20 local time (10:20 GMT), further rain brought the covers back on and delayed the start.
