The Hawks dominated Sunday's match from start to finish, with Eagles gun Elliot Yeo kept quiet as the visitors soared to the 14.10 (94) to 4.9 (33) victory in front of 49,454 fans.
Hawthorn's seventh victory from their past eight games lifted them to within half a win of the eighth-placed Brisbane Lions, giving them a platform to gatecrash the top eight.
But they will be sweating on the fitness of Sicily, whose right shoulder popped out late in the third quarter in a marking contest with Liam Ryan.
"It's feeling all right now. It was a bit sore at the start, a bit innocuous," Sicily told Fox Sports when asked about his shoulder.
"I'm not really sure what to make of it yet, we'll deal with that tomorrow."

Forward Jack Ginnivan was left limping in the dying minutes after copping a heavy bump.
West Coast were also left with injury concerns after ruckman Matt Flynn was subbed off in the third quarter after damaging his right ankle.
In-form forward Jake Waterman limped off during the third quarter with a knee injury, but he was able to return to the field after having it strapped.
West Coast loaded up on height in their forward line, hoping to cash in on the marking power of Oscar Allen, Waterman, Jack Darling and Bailey Williams.
But their first mark inside 50m didn't come until Allen took a grab five minutes into the final term.
The Hawks already had 17 marks inside 50m to their name by that stage, highlighting the difference in class between the two sides.
In reality, it was West Coast's midfield horror show that truly cost the home side.
Hawthorn won the clearance count 38-19, with James Worpel (28 possessions, 11 clearances) and Conor Nash (25 disposals, six clearances) influential.
The centre clearance count was 14-4 in favour of the Hawks, and the inside 50m count (60-33) also made for ugly reading.

Harley Reid, playing his first match since serving a two-game suspension, finished with 21 possessions and four clearances, but committed several turnovers and lacked his usual flair.
Eagles defender Jeremy McGovern stood tall in defence with nine marks and 20 disposals.
Hawthorn won the inside 50m count 17-8 and the clearances 18-9 in a dominant opening quarter, but they failed to get full reward for effort on the scoreboard.
Mabior Chol, Jack Ginnivan, Nick Watson, Jack Gunston and Nash either sprayed shots for a behind or didn't register a score altogether in a scrappy effort in front of goal.
The Hawks still managed to kick the only three goals of the opening term, and they broke even in the second quarter to enter the halftime break with a 17-point edge.
West Coast went from bad to worse in the second half as Hawthorn slammed through nine goals to two to secure the percentage-boosting win.
