Moeen Ali is doubtful for the second Test of Ashes 2015 between England and Australia, which is scheduled to start from Thursday at Lord's Cricket Ground in London. 

Ali was not a part of the training session on Tuesday, but he did bat on Wednesday morning in the nets. If Ali decided to pull out of the Lord's Test match in the last minute, then he will be replaced by Adil Rashid.

The Yorkshire leg-spinner impressed all the fans and the selectors during the ODI series against New Zealand. He was impressive with bat as well. But one would feel that he might not produce what Ali has done for England in the recent times.

His absence could be a blow to England's hope of regaining the Ashes. The player scored a brilliant knock of 77 runs in the first innings of the first Test match at Cardiff. He also picked up five wickets in the Test that England won by 169 runs.

His injury is being monitored by the medical staff. England captain Alastair Cook said that a decision will be taken on Thursday morning whether Ali will be able to play or not.

"He felt his side a tiny bit after the last game and, with his previous history, the medical team were wrapping him in cotton wool. We'll make a final call tomorrow but it was more precautionary yesterday," Cook told the reporters ahead of the second Test of the Ashes 2015.

"I don't think it's the same injury. It's like always when you've got two games back to back, you're a little bit careful with training. But unless he gets a reaction overnight I expect him to be in our side," he added.
