Washington Wizards forward Otto Porter Jr. was diagnosed with a Grade II strain of his right Vastus medialis after undergoing an MRI on Monday, per Candace Buckner of the Washington Post.
The injury in his quadriceps will cause him to sit out at least another week.
The 25-year-old first left the Dec. 10 contest against the Indiana Pacers due to what was believed to be a knee injury, and he has missed the past three games. He was also sidelined for a game in early November because of a bruised left toe.
