Coleman faces as long as 10 months on the sidelines following the horrific injury he suffered in the World Cup qualifier against Wales.
"I asked if Seamus was listening to him and he said, "Yes, to be fair, he was".
Bale was fortunate to escape with just a yellow card from the incident, with the O'Shea seething after watching TV replays of the incident after the 0-0 draw.
"It's a bad blow for the player who has been terrific for us and who has had a wonderful season at Everton".
Burnley midfielder Robbie Brady will captain the Republic of Ireland in Tuesday's global friendly against Iceland in Dublin.
"I think he's just beginning to come to terms with it", said O'Neill to the media at this week's press conference.
The Republic of Ireland global was the recipient of a horrific tackle from Wales' Neil Taylor during their 0-0 draw at the weekend. In total, the scheme is capped at €7.5 million per player.

"It's tough. You don't want to come on in a game like that, especially when that's just happened".
It's unlikely O'Neill will trial out a new system, but instead integrate newer players and offer more options for Ireland off the bench. O'Neill sprung another Preston player, Aiden McGeady, from the bench, but they were unable to capitalize on the pressure.
