Hawks injury report: Zaza Pachulia is questionable with a sore Achilles and Lou Williams is out with a torn ACL.
Celtics injury report: Jared Sullinger (Back) and Rajon Rondo (Knee) are out for the season.
Hawks player to watch: Al Horford has scored at least 20 points in 10 of the last 11 games. He finished with 24 points and 13 rebounds in the win over the Celtics back on January 25. Horford is leading the Hawks at both ends of the court and Atlanta will need another strong performance against the Boston front line.
Celtics player to watch: Its easy to go with Kevin Garnett or Paul Pierce but Jeff Green has played really well of late off the Celtics' bench which is something the Hawks can't overlook Friday night. Green has scored in double figures in seven of his last eight games and had 17 in the double-overtime loss to the Hawks in January.
