This isn't pretty.
Gold Coast Titan player Daniel Mortimer has shared a horrific photo of a gash he suffered after colliding with team mate Ryan James's elbow.
The incident happened just 24 minutes into their clash with the Cronulla Sharks on Sunday.
Don't headbutt Ryan James' elbow. You'll come off second best... #friendlyfire @dark1991
Mortimer was forced to leave the field and is in doubt for the Titans clash against St George Illawarra on Saturday.
