The Boston Celtics and Philadelphia 76ers have built up quite the rivalry in recent years, though the Celtics have mostly dominated on the scoreboard. The two teams will face off once again on Wednesday night, but Gordon Hayward will not be playing due to his status in the concussion protocol:

Gordon Hayward has had an up-and-down season, which isn't surprising considering he's still working his way back from a devastating injury.

On the year, Hayward is averaging 10.8 points, 4.3 rebounds and 3.4 assists per game. Those numbers are well below what he produced when healthy with the Utah Jazz.

Hayward has been extremely inconsistent, throwing out performances where he looks completely lost, only to follow it up with games where he's dominant. This has been the exact story in his three games against Philly.

In their first matchup (a Celtics win), Hayward scored just 10 points on 4-of-12 shooting. He did manage five rebounds and four steals.

In the second game (another Celtics win), Hayward scored five points on 2-of-6 shooting. This time, he didn't add much else to the game, notching two steals to go along with one assist and one rebound.

In their latest matchup (another Celtics win), though, Hayward went ballistic. He shot 8-of-11 (6-of-7 from 3-point land and 4-of-4 from the foul line) and totaled 26 points. The forward added four rebounds, three assists and a steal to the stat line.

This isn't great timing for the Celtics, as they're just 2.5 games back from the Sixers when it comes to playoff seeding. They're currently in fifth place, one game back from the fourth-place Indiana Pacers.
