Sri Lanka may be without two of their fast bowlers as they prepare for what coach Stuart Law believes is the toughest challenge in world cricket.
Nuwan Pradeep has damaged knee ligaments and may leave the tour, while Dilhara Fernando is also struggling with a knee problem.
Sri Lanka have called up Farveez Maharoof, who has been playing for Lancashire, as cover.
The tourists' bowling division has already been depleted by the retirement of Muttiah Muralitharan and Lasith Malinga, and Law has warned his players that facing England in their own conditions is the hardest task in the sport.
"In the last 18 months England have been the best team in world cricket," said Law. "They have beaten teams in their backyard and they've beaten teams away from home.
"They are well-drilled and leave nothing to chance. We are preparing for them to be the toughest deal on the planet. But I would be very surprised if England took us cheaply. Our warm-up games have proved we are going to be competitive. I want our boys to stand up and fight in all conditions and in all situations."
This is Cardiff's second Test after the city hosted the First Ashes Test in 2009 but the interest has yet to match that game against Australia. Although Glamorgan, who play at the Swalec Stadium, are hopeful that supporters will buy tickets at the gate, it is not thought that any of the days is a sell-out.
Meanwhile, former Australia spinner Terry Jenner has died at the age of 66. Jenner played nine Tests between 1970 and 1975 but was better known as Shane Warne's mentor.
