Uh-oh. A small cartilege tear in Lakers center Andrew Bynum’s right knee has flared up after he hyper-extended the knee in Friday night’s series-clinching victory over the Thunder.

The L.A. Times has the details:

The 22-year-old center is listed as questionable for Sunday’s game against Utah because of a small tear in some cartilage in his right knee.

Bynum had been playing pain-free with a smaller tear in the area that worsened slightly when he sustained a hyper-extended knee Friday against Oklahoma City. He might need surgery to repair it after the season.

Bynum played 27 minutes Friday but had only six points and four rebounds. He is day-to-day as the Lakers get ready to begin the Western Conference semifinals against the Jazz.
