Mark Berman of the New York Post reports that the recently-signed Patrick Ewing Jr. will likely have to beat out two other training-camp invitees for the Knicks’ final roster spot:

[Ewing Jr.] is hardly a lock to make the team, but showed flashes during the Las Vegas summer league as he bounces back from knee surgery.

Ewing was cut after training camp in 2008. The Knicks have one open roster spot and plan to sign at least two more candidates, possibly including guard Maurice Ager.

Ager indeed seems like a potential candidate; I first reported the Knicks’ interest in him 10 days ago, though my source said talks between the Knicks and Ager “calmed” after the Ewing Jr. signing. We’ll see how it all shakes out soon enough.
