Quentin, who is with Class A Lake Elsinore on a Minor League rehabilitation assignment, was scheduled to play on Friday for the Storm. He didn't, and later called Black in Philadelphia to say that his surgically-repaired right knee is still bothering him, particularly when he's in his hitting stance.
"The knee is still a little sore," Black said. "He's still having a little bit of discomfort getting in the box and in his stance with the load on his back leg. We decided to take a step back."
Quentin won't play Saturday or Sunday and with the Storm off on Monday, the soonest he could play in another game would be Tuesday.
"He's taking it day by day," Black said.
When Quentin had arthroscopic surgery on his right knee in San Diego on March 19, the initial prognosis was that he would be sidelined between four and six weeks. Quentin later told reporters "I'd like to miss less [time]."
Quentin is currently seven weeks and five days removed from surgery.
The surgery Quentin had was to repair some meniscus tearing and remove loose particles in the knee.
To date, Quentin has played in seven Minor League games, hitting .286. He last appeared in a game on May 10.
Six days ago at Petco Park, Quentin said he was encouraged by his progress. But he didn't play Tuesday or Wednesday for Lake Elsinore before appearing in Thursday's game. He hasn't played since.
"I think we're a lot closer," he said on May 7. "I'm not counting out the road trip."
