FAIRFAX, Va. (AP) Wizards rookie Otto Porter has a right hip flexor injury.

Porter, the No. 3 overall pick, rode a stationary bike as Washington opened camp Saturday at George Mason University. Coach Randy Wittman said the injury has been bothering Porter for a couple of weeks.

The small forward said he slipped and twisted during a recent voluntary pickup game before camp opened.

``Nothing major,'' Porter said, classifying his timetable for returning as ``day by day.''

This is Porter's second injury since joining the Wizards. The former Georgetown star sat out the final two games of the NBA's Las Vegas Summer League with a right hamstring injury.

``He's missing a lot of valuable time out here, in terms of what he's been limited to,'' Wittman said. ``So I mean, we've got to be smart with it. We need to get him healthy as soon as we can.''
