Salah scored in the game after allegedly saying he would do everything possible to "stop the Zionist flag" appearing in the Champions League, Europe's premier club competition.
He has repeatedly denied that making the anti-Israel statements attributed to him at the time of the game.
Chelsea owner Roman Abramovich and director Eugene Tenenbaum are both Jewish and supporters of Israeli causes.
The Premier League club has not commented on Salah's actions.
The controversy is unlikely to reoccur in the near future - Chelsea are through to the knock-out stages of this season's Champions League, but will not face any Israeli opponents until the 2014/15 season at the earliest.
There are also currently no Israeli footballers in the Premier League.
