Tendulkar was injured by a short-pitched delivery from Doug Bollinger during Mumbai Indians' opening IPL match against Chennai Super Kings on Wednesday.
"Finger still not looking good. Had to aspirate blood from my finger twice in 4 days," Tendulkar wrote on his twitter page.
The iconic batsman has also posted a picture of his injured finger on Twitter.
Tendulkar was batting on 16 and had to retire hurt as he was in considerbale pain after being hit on the gloves. He missed the next match against Pune Warriors but is likely to miss a few more matches.
Mumbai Indians play Deccan Chargers later in the evening but as of now there is no certainty as to when Tendulkar will be back in MI colours. PTI KHS MRM
