New Scotland captain Gavin Hamilton faces a race against time to be fit for next month's ICC World Twenty20 tournament.
The 34-year-old suffered a freak hamstring injury during Monday's Friends Provident Trophy defeat at Kent.
But he hopes to be fit for the forthcoming World Cup after being named in Scotland's 15-man squad on Wednesday.
The former Yorkshire and England all-rounder, who only succeeded Ryan Watson as skipper last week, said: "It is all very frustrating, coming so soon after being given the captaincy.
"I tried to stop the ball with my foot while fielding in the ring and ended up stepping on it and the damage was done.
"I have sustained similar problems in my career and it could take a few weeks to sort. Obviously, I hope it is not that serious."
He added: "The tournament will be a huge test for us all, playing some fantastic sides on the biggest stage cricket can offer.
"We have made some positive steps forward in the last couple of weeks and the full squad is looking forward enormously to testing ourselves against the world's best."
Scotland warm-up for the event with matches against England at Trent Bridge on June 2 and Holland at The Oval on June 3.
Their first group games are against New Zealand and South Africa on June 6 and 7, both at The Oval.
