Australia Test spinner Nathan Lyon suffered a "mild concussion" during New South Wales' intra-squad trial game but is expected to be available for next week's Sheffield Shield opening match.
Lyon was withdrawn from the rest of the three-day game on Tuesday as a precautionary measure.
"In NSW's 3-day intra-squad trial match that began yesterday, Test spinner Nathan Lyon suffered a mild concussion and as a precaution has withdrawn from the rest of the fixture," Cricket NSW said.
"Lyon was injured while fielding late in the day, after bowling 20 well executed overs (1/79), and is expected to play in next week's Sheffield Shield opener," it said.
The 33-year-old off-spinner has played in 100 Tests after making debut in 2011 and has taken 399 wickets so far.
