Sri Lanka batman Chamara Kapugedera faces a nervous wait to discover if his Champions Trophy campaign is over after suffering an injury in practice on Wednesday.

Kapugedera sustained the undisclosed injury on the eve of Sri Lanka's second match in the tournament against India at The Oval on Thursday.

Sri Lanka captain Angelo Mathews revealed Kapugedera has gone for a scan to determine the extent of the problem, with a potential replacement on stand-by to come into the squad.

"Yeah he just got injured at training, so we sent him for an MRI scan," Mathews told a press conference at The Oval on Wednesday.

"We are waiting for the doctor's report. If need be, we might have to bring in a replacement."

Kapugedera's injury is the latest blow to Sri Lanka after stand-in captain Upul Tharanga, deputising for the injured Mathews, was banned for the remaining two group matches as punishment for his team's slow over rate against South Africa last weekend.

The 30-year-old middle order batsman, who made his international debut in 2006, was dismissed for nought against the South Africans as Sri Lanka lost their Group B opener by 96 runs.
