Tracy back, Servia retained.

As expected, the Forsythe Championship Racing line-up will change again for next weekend's Mazda Champ Car Grand Prix of Portland, with Paul Tracy having been cleared to return to action following his back-breaking shunt in Long Beach.

The Canadian had always been tipped to return for round four of the series, where he will be partnered by the man who stood in for him at both the Californian street race and the subsequent race in Houston - Oriol Servia.

Tracy has been given the green light to return to the cockpit of his familiar #3 Panoz-Cosworth for a two-day test at Mont-Tremblant this week, having recovered sufficiently from the compression fracture to his first lumbar vertebrae he suffered during practice for the Toyota Grand Prix in April. Renowned orthopaedic surgeon Dr Terry Trammell gave the go-ahead after reviewing the latest X-rays this week, confirming Tracy's decision to begin his recovery process only a couple of days after his accident.

"It feels good to be back in shape and ready to drive," the 2003 series champion admitted, "It's been very frustrating, as we started the year with a strong result in Vegas and we knew we were starting to build momentum. This injury completely interrupted our plans for the championship.

"It's going to be tough coming from behind in the points, but all we can do is go out there, win races, collect as many points as we can and see what happens. The Forsythe team has been working very hard on the development of the DP01 and we've proven that we can be up there fighting for the top spots. Now we'll just have to pick up where we left off and start building our momentum again."

Forsythe also confirmed the expected decision to retain Servia in place of Mario Dominguez, who began the season with a deal for the opening three races. The Spaniard replaced Tracy at Long Beach and Houston, taking second and fourth place results respectively.

"I want to thank Jerry Forsythe and the Forsythe team for putting their trust in me and letting me get back behind the wheel of one of their cars," Servia said, "I'm very glad that Paul is fully recovered, and I hope that, together, we can give Sebastien [Bourdais] a good fight for the victory at Portland.

"These last few weeks for me have been no different for me than any other year. I'm preparing mentally and physically as I always do, always ready to go out there and fight for the championship."
