If there was one sour point for Leeds Rhinos during their game with Wakefield Trinity, it was the sight of Harry Newman limping from the field.
The young centre was going well in his first game of the season and had scored during an opening half blitz of tries by the Rhinos.
But early in the second half he was forced from off after a collision with Wakefield forward David Fifita that left him worse for wear.
Newman visibly felt the contact of the tackle straight away as he went down wincing in pain, and after treatment came off.
Inevitably, the sight of him hobbling off was a cause for concern and Agar confirmed after the game that Newman had felt a tweak in the hamstring that had forced him to the sidelines.
"Harry just in that tackle felt his hamstring a bit so just precautionary," he said.
"Coming back off one we decided to withdraw him, so fingers crossed on that one."
Leeds will be hoping it's nothing more severe, with Richard Agar set to give an update after the game.
Before that, Newman had scored one of five first-half tries for the Rhinos to make his return to the field.
