The Matthew Knight Arena (MKA) is a 12,364 seat, multi-purpose arena in Eugene, Oregon, United States. It is home of the University of Oregon Ducks basketball teams, replacing McArthur Court. It is located on the east side of campus at the corner of Franklin Boulevard and Villard Street, a gateway to campus as people arrive from I-5. The arena was originally intended to be ready for the start of the 2010–11 basketball season, but instead opened for the men's basketball game against the USC Trojans on January 13, 2011. It is named for chief donor Phil Knight's son, Matthew Knight, who died at the age of 34 in a scuba diving accident. The arena cost $227 million and was designed as collaboration between TVA Architects of Portland, Oregon and Ellerbe Becket of Kansas City, Missouri.
