At least Iman Shumpert’s knees are swell.

Knicks coach Derek Fisher revealed Shumpert has been bothered by a strained right hamstring since the second day of training camp at West Point, and wouldn’t definitively say whether the combo guard will play in the preseason opener Wednesday against the Celtics in Hartford, Conn.

Shumpert, who didn’t scrimmage or have any contact during Monday’s practice at their Greenburgh campus, believes he will play. Shumpert has been sitting out some practices, including those at West Point. But the Knicks coaching staff is worried Shumpert’s hamstring issue could linger.

Fisher also said guard Tim Hardaway Jr. is battling hip inflammation. Hardaway Jr., Shumpert and Amar’e Stoudemire, resting his knees, barely participated in Monday’s practices.

“I was telling Shump earlier, for eight months we have to be at our absolute best,’’ Fisher said. “It’s a long season. We can’t rush trying to be so excited for the start of the season.’’

“For sure, we’re not going to risk any player to hurry up to be ready for Wednesday.’’

Shumpert, in the final year of his rookie contract, is aiming to play in the preseason opener. The Knicks will also face the Celtics Saturday at Mohegan Sun in Uncasville, Conn.
