Essendon skipper Dyson Heppell has been sent for scans on Friday morning due to back tightness.

However, it is not expected to be anything serious, with Heppell expected to line-up against Port Adelaide tomorrow.

The 28-year old had just made a successful return from injury in Round 1, having been restricted to just three games last year.

Heppell told reporters on Friday he expects to face Port Adelaide in the Adelaide Oval clash at 4.35 AEDT.

The Bombers will be looking to avenge last week's one-point loss to the Hawks, while Port will be hoping to win their second consecutive game after smashing North Melbourne by 52 points.
