Kaushal Silva will remain under observation in a Colombo hospital after being hit on the head during a Sri Lanka training session in Pallekele.
The 29-year-old was airlifted to hospital as a precaution following the incident - that occurred while fielding - and underwent CT scans to assess any damage.
Luckily, the tests came back clear, but the wicketkeeper-batsman will be kept under observation to ensure he suffers no further problems.
Silva made his Test debut in 2011 and has scored 1,404 runs - including two centuries - in 24 matches, averaging 31.90.
He is expected to be part of Sri Lanka's touring squad for their upcoming three Tests against England in May and June.
