Yorkshire skipper Darren Gough is on the verge of a dramatic comeback for the side's Twenty20 game at Grace Road.
The 36-year-old has made a speedy recovery after breaking a finger in the Championship match against Kent earlier this month.
He trained with the Tykes yesterday and plans a swift return provided the specialist gives the green light today.
Gough said: "I'm keeping my fingers crossed. It's been a lot quicker than people expected and I think even my physio's quite shocked.
"When I rang him up the other day and said I felt like I was going to give it a go he said 'I'm not too sure', because they told me four to six weeks.
"But I said from day one that I'd be back quickly and you know what I'm like, I'm determined to get back.
"It's all down to the X-ray and then we'll see what the specialist thinks."
The former England paceman helped Essex into the semi-finals of the Twenty20 Cup last year and his inclusion in the Yorkshire side would be a massive boost as they bid to make Finals Day for the first time.
Gough added: "If it's up to me I'll play against Leicestershire.
"If it's up to the specialist I'll have to keep my fingers crossed and hope that he goes with me."
Gough's bowling this season has been a revelation as the Tykes have taken the Championship by storm.
And a run in the Twenty20 would provide a fillip for the next round of Championship matches which begins at Old Trafford on July 8.
Gough said: "I'm bowling really well but no matter how well you're playing you can still get hit around the park in Twenty20.
"Luckily I'll get back into some form during this series so I'm right for the Lancashire and Warwickshire games which follow.
"I'm sure that it won't take long. I'm experienced now, I've played quite a while, it's just getting that confidence and rhythm back."
Definitely missing from at least four of the matches is Younus Khan who has been selected for Pakistan in their short tour of Scotland.
He departs on Monday after the sell-out clash with Lancashire at Headingley Carnegie, while leg-spinner Adil Rashid is rested for the early rounds.
