The 35-year-old, who is playing in his 100th consecutive game, pulled a limp while chasing the ball on the field in the final session of Day 2.

Lyon immediately grabbed his right calf muscle and fell to the turf before being helped off the ground by one of Australia’s medical staff.

He’s in his 100th consecutive match, and I know he really wanted to get involved and play his part. Let’s hope he’s okay, but it didn’t look good.

If Lyon is eliminated from the series, Todd Murphy, who made an impressive debut against India in the Border-Gavaskar series, is a prime contender to replace Lyon in the playing lineup.

(He) plays great in net and played very well for India when he got the opportunity, Smith said.

I’ll be sure if he comes in he’ll do a terrific job for us.
