The two clubs clashed for the first time in North America's top flight on the weekend with over 36,000 fans turning out to Qwest Field for the 1-1 draw.
Jewsbury said the crowd would have been even bigger if the venue allowed for it and admitted it was a great feeling to be involved in a true rivalry which began in the United Soccer League days.
"If they opened it up to 70,000, there would have been 70,000 in here tonight," Jewsbury said.
"It's exciting to see the passion of the fans, and that just translates onto the field with the players. It's a great rivalry, and I'm just happy to be here and be a part of it."
And Timbers goalkeeper Troy Perkins concurred with his teammate.
"As an American, you dream about it - to be in a big game that everyone is going to see and you're going to make history," Perkins added.
