After a couple of yawn-inducing early rounds, the NBA playoffs have sizzled during the conference finals. Last night the Lakers won at the buzzer on a Ron Artest short follow of a Kobe Bryant miss. With Los Angeles leading 3-2 in the series, the teams move onto Phoenix for Game Six on Saturday night at 8:30 p.m. That critical game is part of a fantastic weekend (all times Eastern) in sports that includes the French Open and the start of the Stanley Cup finals.

Magic at Celtics (8:30 p.m., ESPN)
Can the Celtics hold Dwight Howard off for one more win? Or will this latest spurt of growth from the league's most imposing big man push Orlando to the biggest playoff comeback in league history? That is the question SI.com's Ian Thomsen is asking on the eve of Game Six of the Eastern Conference finals. The Celtics got a huge break on Thursday when the NBA announced that center Kendrick Perkins would be eligible to play in Game 6. The NBA said that one of the two technical fouls Perkins received in Game 5 was rescinded, thus not prompting an automatic suspension for accumulating seven technicals in the playoffs.

Flyers at Blackhawks (Saturday, 8 p.m., NBC)
The Stanley Cup finals begin Saturday and SI.com's Alan Muir predicts Chicago will win the series in six games. His breakdown of the series can be found here.

French Open (Friday, ESPN 2, 12-6 p.m.; Saturday and Sunday, Noon-3 p.m., NBC)
Plenty of stars will be in action this weekend including Roger Federer, Rafael Nadal, Justin Henin and Serena and Venus Williams as the French Open heads to the third and fourth rounds. You can follow all the action here.
