Newman/Haas/Lanigan Racing have confirmed that Milka Duno will test for them at Homestead this week, but stopped short of announcing the Venezuelan as their third driver.
Although reports in America have linked the 36-year-old female racer to a shock Newman/Haas/Lanigan move in recent weeks, the lack of an announcement led to suggestions that the deal had fallen through.
However the team have now announced that Duno will run alongside Graham Rahal and Robert Doornbos in the first IndyCar Series test of the season.
The potential arrival of Duno, who is expected to bring significant personal sponsorship, at the eight-time Champ Car title-winning team will be regarded as a sign of the tough economic situation facing IndyCar teams.
The former sportscar racer has struggled in two part-seasons of IndyCar with the SAMAX and Dreyer & Reinbold teams, and although she began to feature in the upper midfield on ovals by late 2008, the Venezuelan has been a long way off the pace on road courses so far.
