Warriors provide the first opposition of the new Aviva Premiership Rugby campaign for defending champions Tigers on Sunday, September 7 (2pm).
Ryan, named as director of rugby at Warriors in time for the new season, said: “We look forward to the season. We recognise the challenges we are going to face in the Aviva Premiership.
“We are going to fight really hard and what better place to start than at Welford Road.
“There is no bigger test than going away to Leicester Tigers on the opening weekend.
“They are the champions and could have six British and Irish Lions involved. But we are excited by that fixture and the season ahead.”
Match tickets are released for sale through the Tiger ticket office later this month.
Match ticket sales will be open to season ticket holders requiring extra tickets and to members from July 15. Sales to all other supporters commence on July 22.
Season tickets are also available now.
