The Philadelphia Sixers are trying to snap a three-game losing skid and will have to do so without the services of forward Robert Covington in Sunday night in New Orleans.

According to a source, he has been ruled of tonight's game with what is being called a lower back contusion.

Covington injured his lower back late in the fourth quarter, during the Cleveland Cavilers win over the Sixers on Saturday night. X-rays and a CT scan came back negative on Covington's back, trainers had to attend to examine him before two teammates carried him off the floor and into the locker room.

Covington, who shook off a 0-for-9 game the last time the Sixers faced Cleveland on Nov. 27 to score 19 points Saturday night in the loss at Cleveland.

When asked after the game if he had any update on Covington, Sixers coach Brett Brown said; "nothing".

After tonight, the Sixers are in Minnesota to face the T'Wolves.

Now in his fifth season, Covington came in averaging a career-high 15.3 points per game.

With Covington out of the lineup and Justin Anderson hurt, the Sixers will be lacking three-point shooting and defense from the small forward position.  Newcomer Trevor Booker might get an extended run, along with Timothe Luwawu-Cabarrot.
