Kahne won’t defend Brickyard 400 title

Kasey Kahne will not defend his Brickyard 400 victory because of dehydration issues he said result in an elevated heart rate while he is driving.

Kahne said he felt so poorly he should not have been driving the final 100 laps of last weekend’s Southern 500 at Darlington Raceway. He said he was nauseated, struggled to take in fluids from the midway point of the race and vomited when it was over.

Kahne received fluids in the medical center following Sunday’s race in South Carolina. Regan Smith will drive the No. 95 Chevrolet at Indianapolis Motor Speedway.

Midfielder Jermaine Jones announced his retirement, 11 months after his last match for the Galaxy.

The 36-year-old midfielder, born in West Germany to an American father and West German mother, had four goals in 69 appearances for the United States from 2010-17, highlighted by a tying goal against Portugal in the group stage of the 2014 World Cup.

A member of the youth academies of Bonames, Bad Vilbel and Eintracht Frankfurt, he made his professional debut for Frankurt in 2000-01. He transferred to Bayer Leverkusen for 2004-05, returned to Frankfurt midway through the season, then was with Schalke from 2007-08 through 2013-14, interrupted by a loan to Blackburn for the second half of the 2010-11 season.

Jones spent 2013-14 with Beskitas in Turkey, then played for New England (2014-15), Colorado (2016) and the Galaxy (2017).

Patrice Bergeron and a handful of other Boston Bruins players won’t be going to China for a pair of preseason games this month against the Calgary Flames.

Bergeron is still not 100% after offseason groin surgery. Captain Zdeno Chara, who is 41, isn’t going to avoid wear and tear, Torey Krug is coming off a broken ankle, forward Noel Acciari had sports hernia surgery and Anders Bjork had shoulder surgery.

The Bruins face the Flames Sept. 15 in Beijing and Sept. 19 in Shenzhen.
