Yorkshire seamer Dom Leech suffered an unfortunate knee injury while attempting to prevent a boundary before play was suspended after 23.2 overs on day three of the LV= Insurance County Championship match against Lancashire.
The 20-year-old lost his footing and crashed into the concrete foundations of the Western Terrace at Headingley after preventing a four by Luke Wells, whose 97 not out had helped Lancashire to 411 for two.
Leech was treated for approximately 15 minutes and then taken to hospital with his left leg in a brace. An early tea was called at 2.15pm before umpires Ian Gould and Nigel Llong abandoned play for the day at 4:30pm after two inspections of the bowlers' run-ups at one end, where Jordan Thompson had earlier slipped while bowling.
A Yorkshire statement read: "Play has been abandoned for the day due to unfit and unsafe conditions. Water has risen to the surface in key areas where there has been most activity, including the bowlers' run-ups."
There was no play on the second day of the Roses fixture because of heavy rain so a draw now seems the likeliest outcome – although both teams have qualified for Division One of the next phase of this competition.

England spinner Jack Leach took five wickets as Somerset celebrated securing their place in Division One by putting Surrey under pressure.

Nick Gubbins' unbeaten 137 set Hampshire up to press for victory at Cheltenham as they declared on 486 for seven before Gloucestershire closed day three on 107 for three in their second innings to trail by 150.

Stephen Eskinazi batted with a runner to score a vital 53 not out from 173 balls to boost Middlesex's hopes of beating Leicestershire at Northwood.

Ali Orr's maiden first-class century ushered Sussex into a lead of 293 after they closed on 277 for three against Sussex at Canterbury.

Kiran Carlson and Chris Cooke both notched unbeaten centuries for Glamorgan against Northamptonshire at Sophia Gardens.
