PHILADELPHIA - The 76ers had more success at the Wells Fargo Center than at Boardwalk Hall - even though they still are without Andrew Bynum.

Spencer Hawes scored 17 points and Thaddeus Young had 15 to lead Philadelphia to a 107-75 win over the Boston Celtics on Monday night in its first preseason game in its home building.

The Sixers lost 108-105 in overtime to the Brooklyn Nets on Saturday at Boardwalk Hall in Atlantic City.

The team announced Monday that Bynum, the star center acquired in the offseason from the Los Angeles Lakers, will have an injection in his injured right knee next Monday.

Bynum will receive an injection of Synvisc - a gel-like substance that sometimes provides relief for inflamed tissue. The natural substance is designed to lubricate and cushion the joint. The Sixers said the shot has been a routine procedure for Bynum during the previous two seasons and is unrelated to the bone bruise on his right knee.

"He's progressing, on track to where I think he hoped he would be at this point in time," coach Doug Collins said in a video posted on the team's website.

Bynum will continue with conditioning drills. He has been held out of all basketball activity this preseason as a precaution after receiving knee treatment in Germany. They still expect him to be ready for the Oct. 31 season opener.

Lavoy Allen had 11 points and Evan Turner 10 for the Sixers.

Collins has mixed up his frontcourt rotation with Bynum out. Hawes, the starting center last season before moving to forward with Bynum's arrival, off the bench and made 6-of-10 shots.

Young and Allen started and combined for 11 rebounds and 12-of-21 shooting. Nick Young scored 14 points.

"I think you see we have some depth, which is going to be exciting," Collins said. "We've got some guys off that bench who can play."

Paul Pierce scored 16 points and Brandon Bass added 11 for the Celtics. Kevin Garnett was given the night off.

The Sixers dominated the third quarter to stretch a seven-point lead to 21. They closed the period on a 9-0 run and hit the 100-point mark with 4 minutes, 50 seconds left in the game.
