Pakistan cricketers won't wear their smart watches for the remainder of the first test at Lord's after being cautioned by an International Cricket Council anti-corruption officer.
Photographs on day one of the first test against England at Lord's showed Asad Shafiq wearing a watch, which can transmit data such as text messages and emails.
Although it's unclear whether the transmitting capability was enabled, communication devices are forbidden on the field.

Pakistan's Hasan Ali confirmed that an ICC official had spoken to the tourists.
"I didn't know earlier that anyone was wearing one," Hasan said.
"But yes, an ICC anti-corruption officer came to us and told us this is not allowed. So next time nobody will wear them."
Pakistan dominated the first day after bowling out England for just 184 and battling to 50-1 in overcast conditions.
England lost their last five wickets for just 16 runs after tea as Hasan and Mohammad Abbas shared eight between them.
