Yorkshire are hopeful that Kane Williamson will not miss any cricket for the county after being ordered to get his bowling action tested in Loughborough next month.
The New Zealand batsman, a part-time off-spinner, was reported for a suspect bowling action at the end the second Test against the West Indies in Trinidad on Friday, and he will have until July 12 to be tested.
He is due back in England between July 7 and 9, and the only cricket Williamson could miss is in the NatWest T20 Blast.
Director of cricket Martyn Moxon said: "I don't know what it means in terms of when he is due to be tested. I presume it is just a day, but I'm not sure as yet.
“He's due back between July 7 and 9, and I would hope that it won't impact upon any matches.”
Yorkshire are set to be without Aaron Finch for the T20 quarter-finals in early August should they qualify out of the North Division because he has to go back to Australia for a training camp at the end of July.
Meanwhile, Rich Pyrah struck twice in three balls this morning as Yorkshire made an encouraging start to their LV= County Championship match against Warwickshire at Edgbaston.
The all-rounder was joined in the wickets column by Steve Patterson as the Bears, who won the toss, were reduced to 65-3 in the 27th over before reaching the break at 71-3 from 32.
Yorkshire, handing a debut to 18-year-old Sessay left-arm spinner Karl Carver, got the breakthrough courtesy of Patterson’s fifth ball when Will Porterfield edged to Aaron Finch at first slip, leaving the score at 20-1 in the tenth over.
Pyrah then had Varun Chopra caught behind with a beauty that left him off the pitch with the last ball of the 25th over as the hosts fell to 64-2 before he bowled captain Jim Troughton through the gate two balls into the 27th.
Carver has bowled three tidy overs at a cost of five runs.
