Philadelphia (32-36) at Indiana (34-33) 1:00 pm EST

INDIANAPOLIS (Ticker) -- If the Philadelphia 76ers are unable to right the ship, they just might sink right out of the playoff picture.

The 76ers try to maintain their shaky hold on the eighth playoff spot in the Eastern Conference when they take on the Indiana Pacers on Sunday.

Philadelphia has lost five of its last six games but still leads Chicago by 2 1/2 games for the final postseason spot in the East.

The 76ers' tough stretch included four straight losses without superstar Allen Iverson. The league's second-leading scorer returned to spark the team to a 115-106 triumph over Atlanta on Wednesday, but he shot just 4-of-19 for 17 points in Wednesday's 102-86 defeat to Orlando.

Chris Webber attempted to make up for Iverson's off-night with 23 points and 15 rebounds. Kyle Korver added 18 points for the Sixers, who shot only 38 percent and were outrebounded, 47-33, in losing for the eighth time in 10 games.

Indiana's playoff spot is a bit more secure despite losses in three of its last four games. The Pacers sit in sixth place, one-half game behind Washington and one game up on Milwaukee.

In Friday's 75-72 setback vs. Detroit, David Harrison scored 14 points and Peja Stojakovic added 12. Playing in his second game since missing two months with a torn groin, Jermaine O'Neal managed just eight points on 3-of-9 shooting.

The Pacers had lost five straight meetings with the 76ers prior to a 94-93 victory on March 5. Anthony Johnson scored 18 points to lead Indiana, which got the game-winning layup from Stephen Jackson with 2.9 seconds remaining.
