The last thing the Nets wanted to see yesterday was Brook Lopez on the ground reaching for his right foot.

But that’s exactly what they saw when Lopez, after jumping to contest a Carlos Boozer shot in the paint midway through the second quarter of the Nets’ 142-134 triple overtime loss in Game 4, landed awkwardly, felt to the ground and grabbed at his foot.

This time, however, it proved to be nothing but a false alarm, as Lopez remained in the game and turned in his fourth straight excellent performance of the series in his first postseason trip.

“It was all in the higher ankle area,” Lopez said after scoring 26 points to go along with 11 rebounds, two assists and four blocked shots in 51:16. “It was nothing from a previous injury.”

Lopez’s right foot is the one he injured twice last season, forcing him to sit for all but five games, and that he injured again on Nov. 30 in Boston, causing him to sit out for seven games.
