Pinto has undergone surgery to address his upper-body injury and is expected to be sidelined for approximately four months, Bruce Garrioch of the Ottawa Sun reports.
Pinto will likely only be back, at best, for the final month of the season, so there's no reason for fantasy managers in redraft formats to hang onto him at this point. The 21-year-old forward picked up one helper through five appearances with the Senators before suffering his upper-body injury.
