"Center Al Horford sat out Saturday night's game against Washington with a lower back injury sustained in the team's Friday victory over the Los Angeles Clippers. Horford said he would be ready to play in the Hawks' next game against the Philadelphia 76ers on Tuesday.

After arriving at the Verizon Center on Saturday evening, Horford tested his back, which he injured after getting knocked to the floor on a hard foul by the Clippers' Blake Griffin on a last-second drive to the basket. He was still sore.

"It just didn't feel good enough to play," Horford said.

Horford was OK with the foul, which was called a flagrant foul 1. It gave Horford two technical foul shots and the Hawks the ball after the shots.

"It wasn't a dirty play or anything," Horford said. "He was making a play on the ball, so you can't fault him for that.""
