The Sixers had little left to offer by the end of their eight-game road trip, and it showed in their 109-86 loss to the Spurs on Saturday (see story).
Now, here's a look at some of Sunday's NBA action:
Wizards at Heat, 6 p.m.
While the Eastern Conference-leading Miami Heat appear poised to make a run at a second consecutive title, their rebounding efforts haven't resembled those of a championship caliber club.
Coming off arguably their most disappointing rebounding display of the season, the Heat will surely be looking to control the glass Sunday against the NBA-worst Washington Wizards.
Miami (22-9), which is shooting a league-high 49.1 percent and among the NBA leaders with 103.1 points per game, has thrived in almost every facet aside from rebounding. The Heat rank 29th in the league with 38.7 boards per game, an issue that played a huge role in Friday's 96-89 loss to visiting Chicago.
Miami was outrebounded 48-28 and outscored 20-7 in second-chance points while allowing 19 offensive boards.
Grizzlies at Suns, 8 p.m.
Wins in Phoenix have been hard to come by for the Memphis Grizzlies, and they could find themselves in an even bigger hole if Zach Randolph can't play.

The Grizzlies are hoping to have Randolph available as they try to avoid a 12th loss in 14 road meetings with the scuffling Suns on Sunday night.
Averaging 16.7 points and 12.3 rebounds to rank second in the league, Randolph was scratched prior to Friday's 86-84 loss to Portland due to flu-like symptoms. Marreese Speights - starting in place of Randolph - posted season highs of 22 points and 13 boards for Memphis (20-10), which suffered its fourth defeat in six games despite outscoring the Trail Blazers 46-28 in the paint.
Rudy Gay added 19 points and nine rebounds while Marc Gasol scored 12 to go along with a franchise best-tying eight blocks.
Nuggets at Lakers, 9:30 p.m.
Dwight Howard thinks winning stems from strong friendships, even if it's disingenuous.
That could be why even Kobe Bryant's staggering production hasn't been enough for the Los Angeles Lakers lately.
With Howard's status uncertain due to injury, the Lakers may need to find additional support for Bryant as they host the Denver Nuggets on Sunday night.
Los Angeles (15-17) seemed to be reloading for a run at a third NBA title in five seasons after it acquired Howard from Orlando in a blockbuster four-team, 12-player trade in August.
The move has yet to pay off as expected, even with Howard averaging 17.4 points and 12.0 rebounds while Bryant leads the NBA at 30.5 points per game.
