Game 1 will mark the 68th playoff matchup between Boston and New York, with the Celtics winning 36 of the past 67 games. The Knicks won two of the past three postseason series and have advanced to the second round of the NBA playoffs for the third consecutive season.

Expect Boston to target Jalen Brunson and Karl-Anthony Towns often in the 1st Celtics-Knicks playoff showdown since 2013.

A handful of the NBA playoffs' first-round series have yet to be decided, but we already know a couple matchups for the next one. The Indiana Pacers and Cleveland Cavaliers are both through to the conference semifinals.

LeBron James suffered a left knee injury after colliding with the Minnesota Timberwolves' Donte Dincenzo during the Los Angeles Lakers' season-ending Game 5 loss on Wednesday, according to ESPN's Dave McMenamin. The injury is a Grade 2 MCL sprain with an anticipated recovery time of between three and five weeks, per McMenamin.

The 40-year-old superstar said “I don’t know” when asked after a first-round loss to the Timberwolves how many more seasons he plans to play.
