Philipp, who had previously visited Cal, took a trip to Oregon over the weekend and now has three remaining visits left, and in the last week, has finalized the dates for two of them.
Philipp's visit to Oregon saw the Ducks host Arizona, another one of his top six schools.
"It went good up there at Oregon," said Philipp. "My hosts were Jeremiah Masoli and Fenuki Tupou. It was my first time meeting them, but I remember Jeremiah when he was taking his trip to Arizona. I had met him when I was up there visiting my brother. He is real cool."
Philipp got a chance to see the Oregon facilities that he had heard a lot about.
"The facilities were great, it doesn't really have anything like it around the country," said Philipp. "The campus was good too. They have a good academic support and their business school is really good. Eugene was cold but the city was good. The air was clean and there was no smoke."
Philipp is being recruited to play left tackle by Oregon, a point that they reiterated to him.
"They said that if I work hard and I do good at practice, then I can compete for a spot early. Coach (Tom) Osborne, Coach (Steve) Greatwood and Coach (Mike) Bellotti were the coaches I met with."
Philipp's older brother, Hans, made the trip with Arizona to Eugene, but Philipp didn't talk with him.
"We made eye contact, but I didn't go up and shake his hand. I was on my visit," said Philipp.
Philipp said his top six remains the same: Arizona, Cal, Oregon, Oregon State, Stanford and UCLA.
His prep career came to an end on Friday night when Arroyo Valley dropped their final regular season game, but he'll have one more chance to play before going to college.
"I would have liked to have played in the playoffs but we didn't win enough games," said Philipp. "I'm looking forward to the Army Game and I'm excited about that. I'm going to work out hard for it."
