DALLAS (AP) -- Mavericks point guard Derek Fisher will miss at least three games because of a strained right knee.

He won't play Thursday night against Miami and will skip a two-game trip to Memphis and San Antonio. The team says there is no timetable for his return and Fisher will be re-evaluated next week.

He was hurt in the first quarter of Tuesday's win over the Philadelphia 76ers.

The 38-year-old Fisher is a 16-year veteran who won five championships with the Los Angeles Lakers. The Mavericks signed him three weeks ago because of injuries and spotty play at the point.

Fisher replaced Darren Collison as the starter after signing. He is averaging 8.6 points and 3.6 assists in nine games.
