The rally, presented by El Camino Hospital, will take place next to the SAP Center in San Jose on Autumn Street between Santa Clara and St. John streets starting at 5 p.m.
The Sharks, who entered the playoffs with a 51-22 record, are taking on the Los Angeles Kings in their first game of the playoffs at 7:30 p.m. Thursday.
Street bike freestyle stunt rider Aaron Colton will be on hand with demonstrations and there will be music, giveaways and face painting as well, team officials said.
A Sharks merchandise booth will also be there for anyone who needs new gear for the playoff run.
The Sharks are also encouraging fans to join them in growing playoff beards for a good cause.
The men in teal are joining an NHL tradition into letting their beards grow for the duration of the Stanley Cup Playoffs. And fans can join the hairy crusade called the "beard-a-thon" to help raise money for charity at the same time.
Past beard-a-thons have raised $2.5 million since the Sharks started growing the program in 2009.
