Sunday's tee times for the final round of The Open Championship have been brought forward due to concerns over adverse weather conditions.

The clear skies and light winds that greeted fans at Royal Portrush on Saturday are forecast to be replaced by heavy rains throughout most of the final day.

To avoid the threat of delays, tee times are scheduled to begin around two hours earlier than originally planned in the morning. 

The opening group of the day are now due to go off at 7.32am local time, while the leaders involved in the final round of the day will now begin at 1.47pm.
