It’s a two or three-week hamstring injury for Richmond midfielder Jacob Hopper, the Tigers believe.

Hopper was playing his first game since Round 2 on Anzac Day eve after an injury layoff due to a knee arthroscope but was substituted out of the clash against Melbourne in the third quarter.

In strange scenes, the 27-year-old grabbed at his hamstring but remained on the ground before coming from the field in the following minutes, kicking a drink bottle in frustration and heading down the rooms.

Richmond has now confirmed a “mild hamstring strain” for Hopper.
