Mark Wallace's 14-year run of consecutive County Championship appearances for Glamorgan will come to an end on Wednesday because of a torn calf suffered in the previous Championship match against Northamptonshire.

"A bit of an old man's injury," he said ruefully as he contemplated the end of a run of 230 successive Championship matches.

Wallace sustained the injury while batting against Northamptonshire's fast bowler Olly Stone, pulling up abruptly after taking a couple of steps out of his crease as he attempted a quick single. He was standing in as captain at the time for Jacques Rudolph.

After treatment from Glamorgan's physiotherapist Mark Rausa, he was helped off the field, together with the assistance of the 12th man Jeremy Lawlor.

Wallace was playing his 249th first-class match and 230th successive championship match for the Welsh county in a sequence which runs back to June 13, 2001 when he was a late call-up to replace the unwell Adrian Shaw behind the stumps in Glamorgan's match against Kent at Maidstone.

"I'm probably due an injury to be fair," Wallace said. "I would have taken 230 games in a row when I got called up to go to Maidstone in 2001, so I can't really grumble."

Glamorgan will play their final game of the season against Gloucestershire, winners of the Roayl London Cup on Saturday, in a four-day match at Bristol.
