Worcestershire coach Tom Moody must wait on fitness reports before naming his team for today's Cheltenham & Gloucestershire Trophy second-round tie with Yorkshire at Headingley.
Veteran David Leatherdale has been ruled out with an Achilles strain suffered in Sunday's totesport League win over Nottinghamshire.
Moody also has doubts over Kabir Ali and Jamie Pipe, both of whom missed Sunday's match.
Leatherdale could prove the biggest loss. The Yorkshire-born all-rounder was man-of-the-match when he rescued Worcestershire from defeat with a defiant 80 against Yorkshire the last time the two sides met in this same competition at the same stage two years ago.
Although Worcestershire lost to Gloucestershire in the final for the second year running at Lord's last August, Leatherdale scored 66 as shared a 196-run fourthwicket stand with Vikram Solanki.
Coming to the end of his career, which now sees him double up in the role of the county's commercial manager, 37- year- old Leatherdale knows he is not likely to get too many more return trips to God's own country.
Moody has hopes that Kabir and Pipe will play.
He said: "Pipe's got a hamstring problem and we'll just have to assess it on the morning. But, if he doesn't make it we have a very capable deputy in Steven Davies, who did well when he came in on Sunday.
"Kabir's just not having a lot of luck at the moment. He's now got a niggle at the back of his knee. But it's not related to any of the other knocks he's had. His overall fitness is as good as it's ever been. This is just the way it happens sometimes."
Nadeem Malik stands by to come in as Kabir's replacement but Worcestershire could do with being as near to full-strength as possible to take on the Tykes if they are to stand any chance of being to Lord's for a third consecutive Cup final visit.
Yorkshire are expected to include their international players, England captain Michael Vaughan and Matthew Hoggard, as they attempt to reach the last eight of a competition they last won when they beat Somerset in the final three years ago.
If Kabir does report fit, he will do so on a ground that holds happier memories for him.
On his first visit in the National League four years ago, he recovered well from the shock of being pelted for four boundaries by Craig White in his first over. He had the character to bounce back and take five wickets. It was the ground on which he made his England debut in Tests and as one-day international player.
Moody said: "He certainly has good vibes about playing there. And we're looking forward to having him back.
"We'll need him, too, as it's always a challenge up there and Kabir tends to suit the conditions.
"Headingley perhaps isn't so intimidating a place in domestic cricket as it can be in the international arena. But, while there's always a bit of spectator pressure which can make it a difficult task, we've done well there in the past. And I'm sure we will on Tuesday.
"We've a lot of respect for Yorkshire. We know they've been showing some decent form and they've got Craig White back fully fit again after a year out, which has made a difference.
"But the last time we were there we won," added Moody, mindful of Worcestershire's 39-run totesport League win at Headingley almost a year ago, "and we'll go up there with a positive frame of mind."
