NASCAR team owner Jack Roush, injured in a plane crash Tuesday in Oshkosh, Wis., has been transferred to Mayo Clinic in Rochester, Minn., Roush-Fenway Racing announced Thursday.

Roush remains in serious, but stable condition and will continue to be treated for facial injuries.

Roush, 68, an experienced pilot, was attempting to land at Wittman Regional Airport when the accident occurred. The aircraft split near the fuselage upon impact.

The Raytheon Premier jet, registered to Roush Fenway Racing, was destroyed in the accident, which occurred at about 6:17 p.m., according to the FAA incident report.

The National Transportation Safety Board is conducting an investigation into the accident.

Roush nearly lost his life while piloting a small plane near Troy, Ala., on his 60th birthday on April 19, 2002. He hit a power line and landed upside down in eight feet of water. Roush was not breathing when he was rescued and sustained a broken leg, a collapsed lung and head injuries.

Indy lowers ticket prices for Brickyard 400

Indianapolis Motor Speedway, which according to NASCAR estimates has seen its attendance decline by nearly half in the past three years, announced it would lower ticket prices on select seats for the 2011 Brickyard 400.

Ticket prices have dropped $20 in the lower rows of four grandstands to a range $50 to $65. General admission tickets, which were sold for the first time in 2010 for $40, will be reduced to $30 in advance and $35 on race day.

Prices for some premium seats were increased slightly as part of the new program.

"This new ticket pricing program will make the Brickyard 400 more accessible to more fans while also providing more choices for value-conscious consumers," said Jeff Belskus, Indianapolis Motor Speedway Corporation president and CEO.

NASCAR estimated attendance at Sunday's Brickyard 400 at 140,000, compared with 180,000 in 2009, 240,000 in 2008 and 270,000 in 2007. The Indy 500 in May typically draws an estimated attendance of 250,000-275,000.

"I can't deny that having as many empty seats as we had (Sunday) is a disappointment to me," Belskus told The Associated Press. "But we have a lot of people here and a lot of opportunity here to rebuild this event and bring it back. It's going to take the full effort of everyone here at the speedway and at NASCAR."

Herring to make Nationwide debut at Iowa

Drew Herring, who is coming off a third-place finish in the USAR Pro Cup Series last year, will make his Nationwide Series debut Saturday in the U.S. Cellular 250 at Iowa Speedway.

Herring, 23, will drive the No. 27 Baker Curb Racing car, which had been driven primarily by Greg Biffle earlier in the season and is 10th in the owner standings. The organization had its best finish of the 2009 season at Iowa when Jason Keller finished sixth.

"I've been racing since I was 9 or 10 years old, and this has been my dream to be part of a great team like this and a good group of guys--they're a top-10 Nationwide car," Herring said. "This is one of those deals where it could be a make-or-break deal for me.

"I'm just looking forward to getting there and having that good run I know we're capable of doing."
