Knicks coach Mike D'Antoni didn't offer any specifics on Anthony's issue but said he wouldn't have any trouble focusing on the court Friday.
"He's good," D'Antoni said.
The Knicks host the Denver Nuggets on Saturday.
Saturday night's game at the Garden would be Anthony's first against the Nuggets since he was traded from Denver to New York last February.
Anthony has been battling a right ankle sprain and left wrist injury.
He aggravated the ankle injury in Monday's loss to the Magic but was on the court Wednesday against the Suns. Anthony shot only 5-of-22 for 12 points, however, in the 91-88 loss. In his last two games, Anthony has hit just 28.5 percent of his shots (14-for-49). He said after Monday's game that his shot is "flat" due to the wrist injury.
Despite Anthony's struggles from the floor, D'Antoni said he has no problem with his star small forward's shot selection.
"In his mind, every shot that goes up, he's going to try to make it. You have to respect that," the coach said. "If it becomes an issue, then we'll see. We'll work through it."
The Knicks (6-8) have lost four straight games.
On Wednesday, they scored just 88 points against a Phoenix Suns team that had allowed its last four opponents to score at least 100. New York shot 37 percent from the field against Phoenix and ranks 23rd in the league in offensive efficiency, a measurement of points scored per 100 possessions.
