The 2015 NBA Finals got underway with a tense night of action at Golden State's Oracle Center and Cleveland came away from the contest with more than just a defeat to worry about after a fresh injury scare.

We begin in the NBA where Game One of the 2015 Finals series is in the books. The Golden State Warriors edged a tight game 108-100 after overtime with Steph Curry and Klay Thompson combining for 47 points.
LeBron James managed 44 for the Cavs but failed with a buzzer beater attempt to grab the win in regulation time leaving Cleveland trailing 1-0 in the series.
Sticking with the Finals series and Cleveland are once again sweating on the fitness of Kyrie Irving.
After shrugging off tendinitis in his knee to play last night, the point guard was forced out of the game in overtime when he fell awkwardly on the same knee when driving to the basket against Klay Thompson.
Initial reports revealed no damage to Irving’s ACL or MCL but the team is awaiting further test results.
The All-Star himself admitted after the game that the latest potential set back is a concern:
"You can hear in the tone of my voice that I'm a little worried," Irving told the media in the locker room after the loss.
"I just want to make sure everything is OK, and I'm going to take the necessary steps to see what's going on."
With the Cavaliers needing all the men available to them as they bid to overturn an early set back, the entire franchise will have their fingers crossed that an impending MRI scan comes back clear.
Finally, in the NFL, the New England Patriots had a worrying glimpse into life after Tom Brady yesterday.
Jimmy Garopolo, the man who will replace Brady as starter for the first four games of the 2015 season, threw five interceptions during team OTAs.
Four of the misplaced passes came during two-minute drill practice and will have left the Super Bowl champions hoping for better things as offseason progresses.
