Australia's James Davison will be back in action for Dale Coyne Racing this weekend, in his second outing in the IZOD IndyCar Series.

Davison will take the week of the #18 car for Sunday's GoPro Grand Prix of Sonoma, putting him alongside the team's regular driver Justin Wilson for the second race running after having made his d?but in the series at Mid-Ohio on August 4.

"I'm excited to be back in the No. 18 car at Sonoma. Mid-Ohio was a solid d?but that I came out of pleased and having learned a lot," said Davison. "With some experience now under my belt and added confidence that goes with it, I must aim to go another step forward this weekend. Finishing the race again will be most important."

Davison qualified in 16th place at Mid-Ohio and successfully brought the car home on the lead lap in 15th place by the time the chequered flag came out.

The 26-year-old had the benefit of participating in an open test at Mid-Ohio Sports Car Course before the IndyCar race, and he'll have the same advantage again at Sonoma with all drivers able to take part in a full day of track activity at Sonoma on Wednesday.

Davison has experience of Sonoma going even further back, having finished third in the 2009 Firestone Indy Lights race. The winner of that race was JR Hildebrand, who this weekend will return to IndyCar at the wheel of the #98 Barracuda Racing/Bryan Herta Autosport car having split with former team Panther Racing earlier in the season.

The #4 National Guard Panther Racing car will this weekend be back in the hands of Ryan Briscoe, making his return to the series after fracturing his right wrist at the Toronto double-header in July. It will be Briscoe's final race in IndyCar of the season before he concentrates on his American Le Mans Series commitments for the rest of 2013.

This will also be Davison's last opportunity in the #18, as Dale Coyne Racing have already announced their driver line up for the rest of the year, with Justin's brother Stefan Wilson confirmed as stepping into the car for Baltimore and Mike Conway set for the seat at Houston before Pippa Mann takes over for the season finale at Fontana, making it an all-British line up for Dale Coyne for the last races of 2013.
