The youngster currently on a season-long loan deal from the topflight team has been in blistering form for the English Championship side scoring 21 goals in 38 games.
But the teenage striker picked up an injury in the Robins’ 2-1 defeat at Leeds United last week. And fears of a lengthy period on the treatment table have since been allayed as his coach confirmed he will be out for ‘two or three weeks’.
Abraham returned to the Stamford Bridge for an assessment of the injury.
"He'll be out for two or three weeks," Bristol manager Lee Johnson told Evening Standard.
"Chelsea are taking care of Tammy at the moment. We'll get him back here in a week to ten days."
The Ashton Gate Stadium outfit are currently 21st on the English second division log and will be hoping to get their talismanic striker soon enough in a bid to avoid the drop to the League One.
