All eyes will be on LeBron James and his elbow during Game 3 tonight.

The NBA’s biggest story these days might be LeBron James’ right elbow, the most examined joint in Cleveland sports history which even has its own Twitter account (@LeBronsElbow). (Watch CNN's Sanjay Gupta talk about the injury.) The Celtics and Cavs play Games 3 and 4 in their Eastern Conference semifinals this weekend, the highlights for a busy weekend in sports (all times Eastern):

-Cavaliers at Celtics (ESPN. 7:00 PM) How will the three days of rest affect LeBron’s health? He’s been diagnosed with a bone bruise and strain in his right elbow and the series outcome will likely come down to how hard he can go with the pain. Game 3 is tonight. The series is tied at 1-1.

-Suns at Spurs (ESPN, 9:30 PM)
Why do the Suns lead the series 2-0? Simple teamwork,” says SI.com’s Ian Thomsen. “The Suns are delivering more production and energy across the board.” Phoenix is 34-9 over the last three months and can take a commanding lead tonight in Game 3 in San Antonio.

-Wigan at Chelsea (Sunday, 11:00 AM, Fox Soccer Channel)
It’s simple for Chelsea: The Blues will lift the Barclays Premier League title if they pick up three points at Stamford Bridge. A draw or loss opens the door for Manchester United, who play Stoke City. Chelsea leads Manchester United by a point with only Sunday’s games remaining in the schedule.
