THRILLING THIRD: The Knicks trailed by as many as 20 points in the third quarter and were down 18 with eight minutes to go in the period.
The momentum seemed to be completely on Boston's side, but then the Celts got into foul trouble. Brandon Bass picked up his fifth foul, Kevin Garnett picked up his fourth and Green picked up his fourth in a three-minute span.
From there, Felton took over. He scored 10 points during a 17-7 run to end the quarter, cutting the Celtics' lead to three entering the fourth.
Felton had 16 points in the third quarter.
He added a big jumper with 1:18 to play to give the Knicks their first lead of the game. Garnett tied the score with a jumper and the teams eventually went to overtime.
FORGETTABLE FIRST HALF: The Knicks found themselves down 20 in the third, thanks to an awful performance in the first half.
The Knicks trailed by 19 at the half after shooting just 30 percent from the field and being outscored 17-6 in the final 5:16 before intermission.
Anthony struggled mightily in the first half. He missed his first six shots, finished the half 3-for-15 and turned it over five times. The Knicks entered the game averaging just 11.7 turnovers per game in the playoffs but committed 12 in the first half.
They clearly missed Smith. All Knicks not named Carmelo Anthony went 8-for-23 in the first half.
SUNDAY IS SHUMP'S DAY: Shumpert was key for the Knicks late in the game. He had five points and six rebounds in the third quarter and seven points in the fourth, including a steal and layup to tie the score at 74 and a 3-pointer to pull the Knicks within two (82-80).
WHAT'S NEXT: The Knicks will face Boston in Game 5 at Madison Square Garden on Wednesday.
