Welcome back, Al Horford.

If his game-winning tip-in shot wasn't enough, how about a block at the buzzer for good measure? That's all Horford did in his return to the Celtics' lineup after missing the last nine games.

Horford's tip came with a second left to give the Celtics a 94-92 lead over the Pistons.

Then, with the Pistons in search of an answer, Horford made the game-clinching block on Aron Baynes.

Horford filled up the stat sheet in 34 minutes, scoring 18 points to go with 11 rebounds, five assists, three blocks and two steals.

Head coach Brad Stevens was more than happy to have him back in the lineup.

To say the least.
