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.

“I believe I‘m playing,’’ Shumpert said. “I would hope so. I don’t want to sit out all these practices and not play. That’s why I’m sitting everything out so I can get some game action.”

Meanwhile, Shumpert isn’t sure of the exact diagnosis.

“It’s a strain, pull, something,’’ he said. “I would play, but they don’t want it nagging me all season. Coach is taking the necessary precautions. If it was a bruise, they’d let me play. But since it’s a muscle, I don’t want anything to linger on throughout the season. Just sit out and get through it.’’

The good news is Shumpert’s left knee is no longer an issue, after he tore his ACL and meniscus during the 2012 playoffs. Even at last season’s training camp, Shumpert dealt with a sore left knee and on the eve of the trading deadline, he sprained his left knee, putting him out a few weeks.

“I haven’t paid it any mind at all,’’ he said.

The 2016 salary cap is expected to rise dramatically in the wake of the nine-year, $24 billion TV deal. If the Knicks don’t spend all their cap space in 2015, they will have a huge amount of space in 2016 when Fisher’s former Thunder teammate, Kevin Durant, becomes free.

“I’m sure management feels great having more flexibility in looking how to build this team for years to come,’’ Fisher said.

Fisher said he’s unsure Stoudemire will play the majority of the seven exhibition games. Stoudemire has been limited in practices to save him. “We’re managing him the best way that would be great for him,’’ Fisher said.
