Former West Indies captain Brian Lara says doctors believe his health scare is "nothing major" after he was taken to hospital in Mumbai with chest pain.
Lara, 50, had tests on Tuesday after suffering the pain in the gym but hopes to be discharged on Wednesday.
"A couple of the tests have come back already," said Lara in a message on Twitter from Cricket West Indies.
"The doctors were quite happy that there is nothing major. I'll be back in full health very soon."
One of the finest batsman in the game's history, Lara is in India to perform media duties during the World Cup.
He holds the records for the highest individual innings in both Tests and first-class cricket.
"I think I maybe just extended myself too much in the gym this morning and there's been a bit of pain in my chest," added Lara.
"I'm just letting everyone know I'm fine, I'm recovering and I'll be back in my hotel room tomorrow.
"I'm going to be alright."
Lara is regarded as one of the greatest batsmen the game has ever seen.
He scored 11,953 runs in 131 Tests - which was a world record until he was overtaken by India batsman Sachin Tendulkar in October 2008 - and a further 10,405 in 299 one-day internationals.
In 1994, he made the highest first-class score - 501 not out - for Warwickshire against Durham at Edgbaston and 10 years later compiled a record unbeaten 400 against England in Antigua.
Lara's international career started in November 1990 and ended in April 2007, and included 34 hundreds in Tests and 19 in one-day internationals.
Earlier on Tuesday, a statement on Twitter from Cricket West Indies said: "Our prayers go out to Brian Lara, who has been hospitalised in Mumbai due to chest pains.
"On behalf of all at Cricket West Indies, we wish you a speedy recovery."
