On Saturday night (May 19), the basketball world will be watching Celtics vs Cavs live stream online and televised game coverage. The two teams collide at Quicken Loans Arena in Game 3 of their NBA playoff series. So far, Boston has ruled Cleveland in the Eastern Conference Finals, but most fans know to never count out LeBron James, even when his team's in a deficit. Here's the latest game preview with start time, matchup odds, television channel, and how to watch the Celtics vs Cavs live streaming online.

Game 3 preview and odds

The Boston Celtics got off to a hot start in the first game of the series with a 108-83 win on their home court.

Game 2 was another double-digit win, this time 107-94. LeBron James was held to just 15 points on 5-of-16 shooting in that first game and Kevin Love added just 17. The Celtics were able to hold Cleveland to 36 percent shooting while hitting at a rate of 51.2 percent from the field themselves. So far, the work this Celtics team has done has helped to put the spotlight on their coach, Brad Stevens, for the great job he's done in Boston this season.

In that first game, it was Jaylen Brown leading the way with 23 points on 9-of-16 shooting but Al Horford added 20 and Marcus Morris had 21 points. Morris also grabbed 10 rebounds in the effort which showcased just how solid this Celtics lineup is without its two All-Star players.

However, they'll look to disprove their doubters even more in Game 3 as they'll be on the road in a hostile Quicken Loans Arena. This isn't a must-win for LeBron James, but it's pretty close to it.

The Cavaliers will be favorites of 6.5 points heading into tonight's home game with a moneyline price of -275 to -300.

The visiting Celtics are +225 to +243 underdogs. For tonight's over/under points total, fans are contemplating 207.5 points for the complete game. Over their past 10 games against one another, Boston has a 6-4 record against the spread, but the Celtics are just 4-6 straight up.
