Ben Stokes retired hurt on day two of England's warm-up match in Sri Lanka after being struck on the left arm.
The all-rounder's workload is being managed before the Test series and he did not bowl on day one against a Sri Lanka Board President's XI in Colombo.
During England's reply, Stokes, 27, was struck by a short ball from Lahiru Kumara having attempted a pull.
Pathum Nissanka was then carried off after a Jos Buttler shot struck him flush on the helmet at short leg.
The Sri Lankan fielder, 20, immediately slumped to the turf and received treatment from England's medical staff for about 15 minutes.
They then carried Nissanka off on a stretcher while the players took an early tea.
Stokes made 10 runs off 15 balls and may resume his innings after tea.
The three-Test series begins in Galle on 6 November.

Buttler pulled a ball from spinner Nishan Peiris into the top of Nissanka's helmet
