Sarries reveal new Wembley dates
The league leaders hosted Northampton at Wembley last month, attracting a crowd of just under 45,000, and they will also tackle world champions South Africa at the home of English soccer on November 17.
And they have now added Premiership appointments with Worcester on Saturday, February 13 and Harlequins on Saturday, April 17 to the list.
Saracens chairman Nigel Wray said: "We started something special when 44,832 spectators watched us play Northampton at Wembley in September, and now we are planning to build on that success.
"Once again, we will be offering a fantastic day of great rugby and great entertainment at a great stadium."
Saracens, the only club with a 100% Premiership record this term, begin their Amlin Challenge Cup campaign on Sunday by hosting Italian side Rovigo.
