Boston Celtics head coach Joe Mazzulla enjoyed his front row seat to Al Horford's defensive clinic versus LeBron James and the Los Angeles Lakers

Luka Doncic had a huge game for the Lakers, scoring 34 points in the loss. He also took one of the biggest hits in the game when Al Horford hit him in the face with his knee after throwing down a big dunk in the first quarter.

Fans take to social media to react to Al Horford nearly knocking Luka Doncic out during tonight's Lakers vs. Celtics matchup.

Despite his age, Horford played 37 minutes for the Celtics. He ended up recording 14 points alongside nine rebounds and four assists. On top of that, his defense made life a living hell for the Lakers. Tatum even furthered his point by pointing out how valuable the Florida alum was to them.

We saw this firsthand on Saturday night against the Los Angeles Lakers.
