Tensions have been at boiling point between the two sides since Wednesday night.
San Jose forward Jonathan Cheechoo was knocked out of that game with a sprained knee.
The Sharks believe it was an illegal hit, while the Predators see it as an unfortunate collision that should not have resulted in Scott Hartnell's ejection.
With emotions high, the teams combined for 25 penalties, 10 in the first
period alone, with officials busy separating players.
In Vancouver, the Dallas Stars made a bright start against the Vancouver Canucks.
Jeff Halpern and Joel Lundqvist scored on the opening shift in each of the first two periods, and Marty Turco made 35 saves as the Stars evened their first-round playoff series with a win over Vancouver.
Stu Barnes assisted on both goals for the Stars, who head back to Dallas
tied in the Western Conference quarterfinal. Game 3 is Sunday night.
After playing almost seven periods before losing in the wee hours of Thursday morning, and coming back less than 42 hours to play again, the Stars came out with lots of early energy.
It took them only 24 seconds to get the goal they couldn't through 78:06 of overtime in Game 1, with Halpern scoring on the first shift of the match.
Left alone in the slot after a defensive zone breakdown by the Canucks,
Halpern deflected Sergei Zubov's pass from the point behind a sliding Roberto
It was more of the same to start the second period, with Lundqvist left
unchecked to convert Mike Modano' cross-ice feed just 45 seconds in.
That was more than enough offense for the Stars, who were one of just two teams (Buffalo the other) to win every game they held a two-goal lead in during the regular season.
Dallas was 28-0-0 after getting up by a pair of goals this year.
Ducks tame Wild
At Anaheim, California, defenseman Francois Beauchemin scored two
power-play goals and Ilya Bryzgalov made 30 saves to lead Anaheim Mighty Ducks to a 3-2 win over the Minnesota Wild.
The Ducks went up 2-0 in the best-of-seven Western Conference series,
which shifts to Minnesota for games Sunday and Tuesday.
Beauchemin scored in the first and second periods, and Ryan Getzlaf added a short-handed goal later in the second period.
Then Anaheim held on after Mikko Koivu pulled the Wild within 3-2 on his goal with 4:56 remaining.
Marian Gaborik had a second-period goal for Minnesota.
Beauchemin beat Niklas Backstrom with a slap shot on a power play late in the second period to put Anaheim up 2-1.
Getzlaf made a cross-ice pass to Beauchemin from the top of the right circle, and Beauchemin's shot sailed into the upper right corner of the net.
Getzlaf scored 2:26 later, his first short-handed goal ever in the
Koivu scored from the top of the crease, managing to get off the shot as
he was falling down, and the puck got past Bryzgalov on the glove side.
