Dean Solomon has made a big call — he's pushed Zach Merrett back into the midfield to try and get some drive going for Essendon.

The interim coach had been playing the former skipper off half-back in recent weeks, but it wasn't working today. The Bombers need something forward of centre, and Solomon is hoping Merrett can provide it.

But while Merrett looks to add some bite, there's big trouble for his teammate Archie Roberts. He's come off the ground with what looks like a dislocated shoulder.

Roberts didn't even go through the interchange. He was walked straight to the boundary by Essendon medics and taken straight to the rooms.

Earlier, Ben McKay returned to the field with his head heavily bandaged. The Bombers are copping it from all angles.

The match is being played at the MCG as part of a day to honour Neale Daniher, the former Essendon player and coach who has become a prominent figure in the fight against motor neurone disease. Daniher played 82 games for the Bombers and later coached Melbourne, and his annual 'Big Freeze' fundraiser has become a staple of the AFL calendar.

Essendon are sitting 12th on the ladder, while Melbourne are 8th. A win today would be crucial for both sides' finals hopes.

For the Bombers, the injury to Roberts is a significant blow. The young midfielder has been a consistent performer this season, and losing him for any extended period will hurt their depth.

Solomon, who took over as interim coach after Brad Scott was sacked last month, is under pressure to turn things around. The Bombers have lost their last three games, and the fans are getting restless.

Merrett's move back to the midfield could be the spark they need, but it's a gamble. He's been solid off half-back, but his clearance work and ability to win the ball in congestion are what made him an All-Australian.

As for Melbourne, they'll be looking to capitalise on Essendon's struggles. The Demons have been inconsistent this year, but they have the talent to beat anyone on their day.

The game is still in its early stages, but the signs aren't good for Essendon. They're down a player, their best midfielder is still finding his feet, and they're playing a team that's desperate for a win.

For the fans at the MCG, it's a tough watch. But at least the day is about more than just footy — it's about honouring a legend.
