Anthony's injury will be reassessed in 24-48 hours, Knicks coach Derek Fisher said.
The pain was significant enough that Anthony did not address the media. Anthony will travel with the team to Dallas for Wednesday's game against the Mavericks, but he will visit a Houston doctor first to receive painkillers that are not stored in the arena, the team told reporters.
Anthony played 18 minutes before he landed awkwardly while taking a jump shot. The Knicks originally said his return was questionable.
According to Marc Berman of the New York Post, Anthony received "lots of treatment" on his quad after the team's morning shootaround.
