Essendon's heartening AFL win over Hawthorn could come at a cost, with ruckman David Hille and midfielder Andrew Welsh both set to face match review panel scrutiny.

Hille was reported for crashing into Hawthorn's Clinton Young in the final moments of Saturday night's first half, arriving late after the Hawk had marked.

Bombers coach Matthew Knights said he was "none too impressed" with Hille, because the incident resulted in a 50m penalty which set up a Hawthorn goal.

The ruckman did not appear to make high contact or cause any notable damage to Young, but made little effort to avoid the collision.

The Bombers' big man avoided any penalty for a similar incident in the opening round, when he crashed into Geelong's Jimmy Bartel in a late spoiling attempt.

Welsh was booked for striking Xavier Ellis in the third term, although it appeared he actually kneed the Hawks midfielder.

The Bomber's left knee seemed to make contact with Ellis' groin area in the off-the-ball incident, with the Hawk spending some time afterwards crouched over in pain.

The Bombers also have some minor injury worries.

Knights said key forward Michael Hurley and midfielder Ricky Dyson were both sore after copping knocks to the knee, although both are expected to be fit to play against Port Adelaide on Saturday.

The Bombers will be hopeful Hurley's season is not interrupted, after he struck form with four goals against the Hawks.

It was just his third game of the year, after he missed the first three rounds through a club-imposed suspension.
