LONDON – England's unseasonable warm spell has created an Olympic problem in the most unimaginable place: the swimming pool.

Games organizers are scrambling to ramp up London's rarest July commodity, air conditioning, in hopes of cooling an Aquatics Centre that has drawn complaints from swim coaches in recent days. The recent string of sunbathed 80-degree days are being described as a heat wave by London locals, and it has harangued a pool deck with equipment failures in recent days. With temperatures approaching a humid 85-degrees, officials are working to cool the environment for what has become one of the most blistering event tickets in these Games.

FINA, which governs the pool at Olympic events, are overhauling the air conditioning system in hopes that the climate surrounding the pool will get down to the upper 70s by Saturday. That's when USA's Michael Phelps and Ryan Lochte will kick off the swim events in the

The NCAA is set to levy the first presidential sanctioning in the association's history on Monday when it will impose what one source termed "significant" and "staggering" penalties against the Nittany Lions' football program in the wake of the Jerry Sandusky scandal, Yahoo! Sports has learned.

NCAA president Mark Emmert will announce the Penn State sanctions on Monday. (AP)Two sources with knowledge of the Penn State penalties said NCAA president Mark Emmert will announce Monday that he is personally sanctioning Penn State after receiving approval from the association's Division I Board of directors, which is comprised of 22 college presidents and chancellors. One source told Yahoo! Sports that Emmert's sanctions will include a "multiple-year" bowl ban and "crippling" scholarship losses.

The move will mark a first in NCAA history, in which the president will invoke a defense of the NCAA's constitution as part of his reasoning for taking the unprecedented steps. The moment is groundbreaking in that Emmert is circumventing typical NCAA process and moving

Less than one week after the University of Miami hired Al Golden as coach, members of Golden's coaching staff began using Sean "Pee Wee" Allen – a then-equipment manager and onetime right-hand man of convicted Ponzi schemer Nevin Shapiro – to circumvent NCAA rules in the recruiting of multiple Miami-area players, Yahoo! Sports has learned.

Golden, hired by Miami in mid-December 2010, had direct knowledge of Allen's improper involvement with Miami recruits, according to a former Hurricanes athletic department staffer and federal testimony given by Allen in Shapiro's bankruptcy case. Additionally, multiple sources interviewed by NCAA investigators have told Yahoo! Sports that Allen has become a focal point in the association's probe into Miami athletics. The sources said investigators focused on Allen's role in providing impermissible benefits to Hurricanes players, as well as his contact with Miami recruits.

Michael Johnson celebrates his world record in the men's 200 meter final. (AP)The golden shoes still resonate.

In the 16 years since they left Michael Johnson's feet, they have mostly done celebrity appearances solo. They have done television spots and toured the country – an orthopedic circus show for the masses. They were displayed under glass in Las Vegas, going glitter-for-glitter with the rest of Sin City. And they have even fueled engineering debates about their exact weight and composition.

If you saw the 1996 Atlanta Olympics, you know these shoes as well as any pair you have ever owned. You can close your eyes and see them, along with the whirring golden blur they projected from Johnson's feet in those games. Weighing 6.8 ounces, and with five grams of gold weaved into their fabric, they were rivaled by only one other accessory worn by Johnson in those games: the 500-gram twin gold medals in the 200 and 400 meters, a feat that remains one of the greatest accomplishments in U.S. track and field history.

Not only did Johnson become the only Olympian

Yahoo! Sports initially stated in its March 12 report on the North Carolina football program that former Tar Heel wide receiver Hakeem Nicks had been disassociated by the university as part of NCAA sanctions released on Monday. The initial report was incorrect.

While Nicks was found by UNC to have provided $3,300 in improper benefits to North Carolina players, he has not been disassociated from the program. Letters of disassociation were sent to the following individuals: former player Chris Hawkins, tutor Jennifer Wiley and jeweler A.J. Machado.

Yahoo! Sports apologizes for the error.

Suspended Auburn University point guard Varez Ward is under investigation by federal authorities in an ongoing point-shaving probe, Yahoo! Sports has learned.

Three sources with knowledge of the case said the FBI has been investigating Ward since late February after he and guard Chris Denson were suspended by the Tigers prior to a Feb. 25 home game against Arkansas. Two sources said Denson was also questioned as part of the point-shaving investigation, but he was cleared of any wrongdoing and returned to the team after sitting out the loss to the Razorbacks. The sources said additional players have been questioned in the case about whether Ward – who has not been with the team since being suspended – attempted to enlist them in a possible scheme. The sources said at least two games are under scrutiny: a 68-50 loss to Alabama on Feb. 7 and a 56-53 loss to Arkansas on Jan. 25.

Nevin Shapiro and a second source said this photo of the booster and Kellen Winslow Jr. was taken in Shapiro's VIP section of Opium Garden nightclub in 2003.

KEARNY, N.J. – A University of Miami booster, incarcerated for his role in a $930 million Ponzi scheme, has told Yahoo! Sports he provided thousands of impermissible benefits to at least 72 athletes from 2002 through 2010.

In 100 hours of jailhouse interviews during Yahoo! Sports' 11-month investigation, Hurricanes booster Nevin Shapiro described a sustained, eight-year run of rampant NCAA rule-breaking, some of it with the knowledge or direct participation of at least seven coaches from the Miami football and basketball programs. At a cost that Shapiro estimates in the millions of dollars, he said his benefits to athletes included but were not limited to cash, prostitutes, entertainment in his multimillion-dollar homes and yacht, paid trips to high-end restaurants and nightclubs, jewelry, bounties for on-field play (including
