A smart chip and chase in-behind from Andrew Kellaway is gathered by Mac Grealy for the goal-line dropout.
Both players come together briefly as tensions flare but it's minor.
What's more concerning is Pete Samu slipping and holding his knee, the number eight is in agony as he tries to play on.
An early chance goes begging as Jack Bowen misses an early penalty to the left.
The conditions don't help his case as the ball falss off the tee right before he's about to kick, having to quickly put it back on and go quickly
