Monday Sports Update: Johnny Sexton To Undergo Scan On Facial Injury.

Old Firm derby takes place this afternoon.

RUGBY

Leinster captain Johnny Sexton will undergo a scan to determine the extent of a facial injury he picked up in last night's win over Connacht.

Leo Cullen's side won the U-R-C derby by 41 points to 12 at the RDS - but Sexton was replaced in the second half.

It's understood the injury is in the cheekbone area.

Sexton's fitness will be a concern ahead of Ireland's Six Nations campaign, which begins in just over a month's time.
