Golf • Vijay Singh sued the PGA Tour on Wednesday, a week after his doping case was dropped, claiming it damaged his reputation by not doing a thorough job of researching his use of deer antler spray.

"I am proud of my achievement, my work ethic and the way I live my life," Singh said in a statement. "The PGA Tour not only treated me unfairly, but displayed a lack of professionalism that should concern every professional golfer and fan of the game."

The lawsuit says the tour had planned to suspend Singh for 90 days.

Appeals board eases JGR penalties

NASCAR • A NASCAR appeals panel sided with Joe Gibbs Racing on Wednesday and eased some of the penalties imposed for having an illegal part in Matt Kenseth's race-winning engine at Kansas last month.

NASCAR punished JGR after discovering during a post-race inspection that one of eight connecting rods in the engine at the April 21 race did not meet the minimum weight requirement. The part was too light by 3 grams, less than the weight of an envelope.

JGR did not dispute the part was illegal, but argued the penalties were too severe because it leases its engines from Toyota Racing Development and is not permitted to touch anything inside of them. Toyota accepted responsibility and insisted one light rod did not give Kenseth a performance advantage.

Happ goes on DL with skull fracture

MLB • Less than 24 hours after he was hit on the head by a line drive and carted off the field, Toronto Blue Jays pitcher J.A. Happ was back at Tropicana Field on Wednesday for a news conference.

The 30-year-old said he had a skull fracture behind his left ear that doctors believe will heal on its own, as well as a sore right knee that he tweaked when he dropped to the ground Tuesday night.
