1. NFL suspends Ray Rice amid ‘knockout’ uproar

The Baltimore Ravens announced Monday they were dropping Rice after new video surfaced showing him knocking out his now-wife in an Atlantic City casino elevator. In addition, the NFL said it was indefinitely suspending the 27-year-old running back.

The NFL’s and the Ravens’ decision is being criticized by people who think officials didn’t do a thorough enough investigation. Read more at NBC SPORTS.

2. Flight MH17 broke apart after ‘high-energy’ impact: report

Almost two months after Malaysia Airlines Flight MH17 was shot down over eastern Ukraine, a preliminary report has found the airplane broke up midair by “high-energy objects.” But the investigation stopped short of saying a missile downed the plane, although U.S. intelligence is blaming a ground-to-air missile used by pro-Russian separatists.

3. What to iWatch for in Apple’s unveiling

It’s that time of year again. The Silicon Valley tech giant is expected to show off its latest gadgets: the iPhone 6 and the iWatch.

The 5.5-inch "phablet" (phone + tablet) will feature a one-handed mode option, according to the New York Times. But it’s the iWatch that may end up stealing the show. The unveiling takes place at 10 a.m. PT (1 p.m. ET). Read more in TECH.

Cilic took home his first Grand Slam title on Monday night after sweeping Japan’s Kei Nishikori in three sets, 6-3, 6-3, 6-3. The 14th-seeded Cilic and 10th-seeded Nishikori earned their first career Grand Slam finals berths by ousting favorites Roger Federer and Novak Djokovic in the semifinals Saturday.
