ATHENS, March 2 (Reuters) - A late goal from Helder Postiga gave Panathinaikos a 1-1 draw against AEK Athens in the Greek Super League on Sunday and allowed them to move one point clear at the top of the table.
The Portugal striker scored his first league goal for the club 12 minutes from time to cancel out Rivaldo's controversial penalty in the Athens derby.
Olympiakos striker Lomana LuaLua suffered a dislocated shoulder in the closing stages of his side's 1-1 draw with Asteras Tripolis on Saturday, club officials said on Sunday.
Olympiakos medical staff realigned the shoulder but a scan subsequently revealed that substantial damage had been done.
LuaLua is now almost certain to miss the Champions League game against Chelsea game on Wednesday and could be out of action for the rest of the season.
"The player's left shoulder has been put in a special cast and he will be re-examined on Monday before we decide on what therapy to follow," the club said in a statement.
Panathinaikos now have 50 points, one more than Olympiakos.
Aris Salonika kept up their bid for a Champions League playoff place with a 2-0 win over Atromitos thanks to goals from Koke in the first half and Amoroso in the second.
Panionios also boosted their hopes with a 2-1 win away at Xanthi. Former Inter Milan striker Lampros Choutos scored a goal in each half while Stavros Lambriakos got one for the home side.
At the other end of the table Apollon Kalamaria helped their hopes of survival with a 1-0 win over fellow strugglers Veria while Levadiakos slumped to a 3-0 home defeat against OFI Crete.
