After the game, USC coach Andy Enfield said the length of Porter's suspension is indefinite.
"He was suspended for conduct issues," Enfield said, according to a report by the Los Angeles Times. "We'll reevaluate his future with the program this week."
Porter said in a statement released Monday that speculation that he won't finish the season with the Trojans is false.

Porter scored five points in 25 minutes in USC's 79-74 overtime loss to Oregon State on Thursday after missing seven consecutive games due to a thigh injury. He arrived at USC as ESPN's No. 40-ranked overall prospect in the class of 2018 and was the top-ranked player from the state of Washington.
Porter scored at least 12 points in each of the first five games of the season but has missed nine of the 11 games since, registering just 29 minutes over the two appearances.
Teammate Jordan Usher was also suspended earlier this season, which led him to transfer to Georgia Tech.
"We've had a lot of distractions this season for a variety of reasons," Enfield said. "The last thing you need is a team that's trying to put together some wins in the Pac-12 to have more distractions."
Usher, from Canton, Georgia, averaged 8.6 points and 3.7 rebounds in 12 games, including two starts. He averaged 4.8 points and 2.0 rebounds as a freshman in 2017-18.
