Multiple web search results report that CJ McCollum made contact with Jalen Brunson, specifically mentioning a 'groin kick' or 'low blow' incident at Madison Square Garden involving the two players. The evidence points to this specific type of interaction.

One web search result provides a highly specific account matching the claim: 'During the second quarter of the Knicks’ 113-102 Game 1 win over the Hawks on Saturday night, McCollum was given a technical for kicking Brunson right in the midsection while taking a jump shot (he was also called for a travel on the play).' This specific detail is corroborated by the general context of the incident reported in other sources.

Two separate web search results describe Brunson staying on the ground in pain after an incident. One mentions him 'stayed on the ground in pain and grabbed at his lower right leg,' and another references him suffering a 'scary injury moment' in Game 1.

Multiple web search results directly quote or paraphrase McCollum accusing Brunson of exaggerating the injury, using the phrase 'milking it' or discussing the 'Broadway show' performance in relation to the injury.

Two separate web search results confirm that CJ McCollum scored 26 points in the game against the Knicks. One source states: 'CJ McCollum had 26 points and Jalen Johnson added 23 for the Hawks...' and another source mentions the context of the game where this scoring occurred.
