Brock Nelson had a goal and an assist to lead the New York Islanders past the Blackhawks 3-1 on Tuesday night for their fourth straight win after Chicago starting goalie Alex Stalock left early in the first period with a potential concussion.

Anders Lee also scored and Zach Parise added an empty-netter for New York.

Ilya Sorokin made 21 saves and lost a bid for his second shutout in three starts when Jonathan Toews scored a power-play goal on a deflection midway through the third period.

The Islanders are on a roll after dropping three straight. They edged Chicago in a tight one after rallying from a three-goal deficit to beat defending Stanley Cup Champion Colorado 5-4 on Saturday.

Rookie Arvid Soderblom stopped 28 of 30 shots after Stalock exited, but the Blackhawks generated few chances against tight-checking New York as they dropped their fourth straight (0-2-2).

Nelson has four goals in three games after not scoring in his first seven. Sorokin has blocked 97 of the last 100 shots he's faced over three games, but credits his teammates.

Stalock exited just 2:56 into the first after he was rammed into the right goalpost by Casey Cizikas. Stalock was placed in concussion protocol and will be re-evaluated on Wednesday.

The Blackhawks were already without top goaltender Petr Mrazek, who has a groin injury. Soderblom is the only other goalie the team has under contract, so Chicago is searching for another.

The Blackhawks hosted an elaborate celebration, complete with Native American dancers and music, before the game the United Center to kick off Native American Heritage Month.

The Blackhawks got their name in 1926 from team owner Frederic McLaughlin in honor of the U.S. 86th Infantry Division, nicknamed the ''Black Hawk Division'' after a Native American chief from Illinois. McLaughlin served in the division in World War I.

While some other sports teams with Native American themed names have come under pressure to change their names or logos, the Blackhawks have said they don't plan to.

The Blackhawks placed top defenseman Seth Jones (broken right thumb) on injured reserve retroactive to Oct. 29 and recalled D Alec Regula from Rockford of the AHL. Jones, who leads Chicago with 25:12 of ice time per game, is expected to miss 3-4 weeks after being struck by a shot in a 4-3 loss at Buffalo on Saturday.

The Blackhawks host Los Angeles on Thursday.
