Shaun Tait has been added as a standby player to the Australian squad for fifth and final ODI against Pakistan.

The South Australian fast bowler Tait will join the current squad of 13 Sunday morning with Peter Siddle, who is still suffering from some back soreness, in doubt for the match.

Australian team physiotherapist Alex Kountouris said: "Peter Siddle is still being troubled the back pain which kept him out of the third match of the series in Adelaide.

As such he is in doubt for tomorrow's fifth ODI and therefore another fast bowler has been included as a standby player.

"Peter will continue to be monitored over the next week before any decision is made on his availability for the KFC Twenty20 International in Melbourne next Friday."

NSP Chairman Andrew Hilditch said: "Shaun Tait at his best is a destructive fast bowler in both limited-over and Twenty20 cricket.

"He has progressed well this season and performed well in both the KFC Twenty20 Big Bash and the recent Ford Ranger game against New South Wales in Wollongong and we are sure he will be ready should he be required for tomorrow's match."
