Scheckter skips Gateway
South African's IRL future placed in doubt
The starting lineup for the Gateway Indy 250 Indy Racing League event contains one major omission - Tomas Scheckter. The mercurial rookie, winner at Michigan and a frequent crasher elsewhere, informed the team he would not be racing this weekend. This was surprising news to the team, which arrived at Gateway fully intending to run three cars again for Eddie Cheever, Buddy Rice and Scheckter.
Team owner and driver Cheever said: "After not showing up for a scheduled technical briefing yesterday, we called and were informed by Tomas that he was not going to participate in the race this weekend. He did not offer any further details. This news was very shocking after the time and effort that both Red Bull Cheever Racing and TWR have put into preparing his car for this race, as we have done all season."
Other reports have suggested that Scheckter has resigned from the team, citing concerns about safety.
Cheever implied that further action would be forthcoming. "We have a contract with Tomas through 2003 which we fully intend to enforce. Although this is a surprise, it will not have a negative impact on our performance this weekend."
