"He (Russell) played in that warm-up game a couple days ago, and it was just like a trial for him because he hadn't played a cricket match in about three weeks, three to four weeks," said West Indies captain Kieron Pollard on Friday.
"Let's see what transpires in this last (training) session."
West Indies beat England in a thrilling final when the tournament was last staged five years ago.
England were on the brink of victory only for Carlos Brathwaite to hit four sixes in a row off Ben Stokes in the last over in Kolkata to give West Indies the title.
'Never say die'
Both all-rounders will be missing, however, from Saturday's match.
"In terms of having a bearing (on Saturday's match), I don't think so, but it's definitely going to be in the back of their (England's) minds," said Pollard.
"I thought what Carlos did in those four deliveries in that last over, it's unbelievable. It's something that as a team we actually saw last night, and it brought goosebumps back to us.
"For us to be in that situation and get over the line, it shows that sort of never-say-die attitude. We as a team, we look forward to trying to replicate winning the entire tournament, but those sort of moments sort of stick with us," added Pollard, who was confident the West Indies would "move on" from their poor warm-up form.
Morgan, speaking earlier Friday, insisted top-ranked England had no scars from their 2016 reverse as they looked to add the T20 global crown to the 50-over World Cup title they won under his leadership two years ago.
"I think if they were scars we would have lost a lot of players who wouldn't have progressed like they have done over the last four or five years," he said.
The former Ireland batsman said adaptability would be the key to success in a tournament which will now take place on a trio of United Arab Emirates pitches in Abu Dhabi, Dubai and Sharjah that may lack pace and aid spin.
"The side who adapts to all three venues the best throughout will go on and win," explained Morgan. "Within our squad we have the ability to do that, we obviously have to be on top of our game, adapt well and be confident with it."
