Sean Collier (AP)Sean Collier, the officer at MIT who according to authorities was killed by the two suspects in the Boston Marathon bombings, was the brother of Andrew Collier, a machinist in the engine department at Hendrick Motorsports.

"The thoughts and prayers of everyone at Hendrick Motorsports are with Andrew Collier and his family," the team said in a statement. "Andrew, a machinist in the Hendrick Motorsports engine department, tragically lost his brother, Officer Sean Collier, last night in Cambridge, Mass. We ask that the family’s privacy be considered during this difficult time."

"A very sad time, my thoughts and prayers are with the family, and I certainly know it's the same throughout Hendrick Motorsports," Jimmie Johnson said. "We're one big family and it's sad and unfortunate to see a fellow teammate and his family have such a tough time."

Collier, 26, responded to a disturbance on the MIT campus on Thursday evening. He was found shot in his vehicle when other officers responded to the

This is a pretty cool gesture from the Michael Waltrip Racing teams to honor the victims of the Boston Marathon explosions at Kansas. The numbers on the side of the cars of Clint Bowyer, Martin Truex Jr. and Mark Martin will be emblazoned on a replica Boston Marathon Racing bib.

Team owner Waltrip ran the event in 2000.

“The news coming out of Boston this week was very personal to me,” Waltrip said in a statement. “When I ran the Boston Marathon in 2000, I remember thinking about what a privilege it was to be able to participate and all the hard work it took to be there. When you can see those international flags flying in Copley Square, you know you are about to complete your journey. I know the joy those runners were feeling at that moment when their worlds changed."

In addition, Roush Fenway Racing, of which 50 percent is owned by the Fenway Sports Group, will run a decal with the Boston Red Sox logo and the word "strong" below it on each of its cars.

Welcome to Warped Wednesday. On this, we'll put out the rush to judgment mat, go a little too far and have a little fun. Will it be funny? Sometimes. Will it be crazy and largely unbelievable? Probably. Will not everyone get it? Definitely.

Reacting to the penalties that NASCAR levied against the Penske teams on Wednesday, sources exclusive to Yahoo! Sports' Warped Wednesday have learned that all teams in the Sprint Cup Series garage are returning to stock car racing's roots.

Both Brad Keselowski and Joey Logano were docked 25 points and crew chiefs Paul Wolfe and Todd Gordon were, among others suspended for six races. The crew chiefs were fined $100,000 as well, all for the setups that the cars had in their rear end housings.

When NASCAR Vice President of Competition Robin Pemberton discussed the confiscation of parts from the Penske teams on Saturday, he said that what they had done to the backs of the cars was "not in the spirit" of NASCAR rules. There's no word if that spirit

On Wednesday, NASCAR issued penalties to both Penske teams that could deal significant blows to the championship and Chase hopes of Brad Keselowski and Joey Logano.

In separate decisions, NASCAR also handed down penalties against Martin Truex Jr. and Ron Hornaday.

The Penske teams' penalties were severe and long-reaching, and stemmed from violations of NASCAR's Sections 12-1; 12-4J and 20-12. Both teams' crew chiefs, car chiefs, engineers and competition directors were suspended for six races, including the All-Star Race in Charlotte. The crew chiefs were fined $100,000 apiece. And both teams lost 25 championship points, which drops Keselowski from 2nd to 4th and Logano from 9th to 14th place.

The penalties will cause considerable difficulty for both teams as they prepare for the Chase. While Keselowski, the defending champion, remains in solid shape to make the Chase, Logano was in the midst of his best season ever. Logano now finds himself outside the Chase, fighting for a highly

What's Brad explaining to President Obama? You know the drill, drop us a line in the comments.

It's time for Power Rankings! After every race, we'll opine about who we think is at the top of the Sprint Cup heap and how and why they got there. Remember, this isn't scientific, as our formula is the perfect blend of analytics and bias against your favorite driver. So let's get on with it, shall we?

1. Jimmie Johnson (LW: 1): At one point during Saturday night's NRA 500, Fox TV analyst Darrell Waltrip opined that the rest of the field needed to capitalize on Jimmie Johnson's struggles. He was sixth at the time. Waltrip quickly corrected himself, seemingly after taking a glance at the scoring monitor or getting word from the production truck that Johnson was much closer to the front than he was to 20th. But such is the NASCAR world that we live in where the first instinct is to call running just outside the top five a "struggle" for the 48 team.

2. Kyle Busch (LW: 5): Hello, Kyle. You've got some elite company above and below you. We're not doubting that you belong here by any means,

NASCAR has a chance to set a precedent for penalties for violations with its new Sprint Cup Series car. And it can possibly reinforce one for crashing a driver under caution. But before those rulings have been announced, the lines for what can and can't be said about the sport by its drivers have become muddled even further.

Saturday night, after the conclusion of the NRA 500 at Texas, defending Sprint Cup Series champion Brad Keselowski was outspoken in his frustration with how he feels his team has been targeted. Before the race, NASCAR officials had the Penske teams make modifications to the rear-end housings on its cars, after NASCAR Vice President of Competition Robin Pemberton said that what the Penske cars had done to their cars was "not in the spirit of the rule."

After finishing ninth, Keselowski said to a group of reporters that "There's so much stuff going on you have no (expletive) idea what's going on. And that's not your fault and that's not a slam on you. I could tell
