Jayson Tatum admitted to having "just one of those nights" after scoring 50 points to help the Boston Celtics strike back in their series against the Brooklyn Nets.

The Celtics found themselves in a 2-0 hole in the playoffs after successive defeats in Brooklyn, during which Tatum managed a combined total of 31 points.

His Game 2 contribution was cut short at 21 minutes after he suffered a poke in the eye, the injury ruling him out as the Nets prevailed 130-108 to double their advantage.

However, Tatum had no issues seeing the basket on Friday when the series switched to Boston, going 16-for-30 shooting from the floor as he reached a half-century of points in a 125-119 triumph.

"It's just one of those nights." Tatum said afterwards.

"A tough shooting night the first game and I didn't get to play much the last game because I got poked in the eye."

His performance makes him just the third Celtic to score 50 in a regulation playoff game, following in the footsteps of John Havlicek (54 in 1973) and Sam Jones (51 in 1967).

Isaiah Thomas was the previous Boston player to achieve the milestone in a playoff contest, managing 53 in an overtime victory over the Washington Wizards in May 2017.

For Celtics head coach Brad Stevens, it was just the latest example of Tatum's undoubted talent.

"He is so advanced for 23 years old; I’ve said the word 'special', and I don’t say that very often, obviously," Stevens told the media.

"But he just has a unique ability to score the ball, to slither through screens and find angles to score, but also the vision to make every right move.

"He was super tonight, but he's been like that a lot this year. He's special."

The game marked Kyrie Irving’s first appearance with fans present in Boston since his departure in 2019. The point guard was booed by the home crowd throughout proceedings as he finished with 16 points and six rebounds.

Irving left in free agency after two seasons with the franchise, opting to move closer to New Jersey for family reasons as he signed with the Nets.

"It's basketball. I've been in a few environments in my life," Irving said about the reaction he received.

"Like I said, as long as it's just strictly the nature of basketball out there and there's nothing extra, I'm cool with it."

James Harden led the way with 41 points for the Nets, while Kevin Durant had 39. Game 4 of the first-round series takes place in Boston on Sunday.
