The Wolves striker declared himself unavailable for the national team via text message in February but has now been urged by his club boss Mick McCarthy to call Scotland manager Craig Levein so he can again be involved.
But even if Levein was happy to have Fletcher back, his Wolves teammate Berra insists it won't be a walk in the park to return to the line-up.
"Steven has said that what happened is in the past. I hope it's been wiped clean now," the centre-half said.
"He's been injured for the past month but if he comes back and starts banging in the goals for Wolves then I don't see why he couldn't be back in the Scotland squad.
"He wouldn't just walk into the team, though. We have a lot of good strikers.
"We also saw Jordan Rhodes involved. So there is real competition for places in that department."
