Rovers have revealed Sam Gallagher has suffered bruising on the lung, known as pulmonary contusion, but was released from hospital on Saturday night.

Gallagher was taken to hospital at half time of Saturday’s 1-0 defeat at Nottingham Forest having been coughing up blood at the interval after falling awkwardly late in the half.

There was concern the 25-year-old he had suffered a punctured lung, but scans showed he has suffered severe bruising.

He is however, expected to face several weeks on the sidelines, despite the injury not being as bad as first feared.

A club statement read: "Rovers have been boosted by the news that Sam Gallagher’s injury is not as bad as first feared.

"Scans have revealed that the 25-year-old has sustained severe bruising to his lung, which is expected to keep him out for several weeks.

"Rovers look forward to welcoming the striker back to action next month once he has made a full recovery."

Posting on social media platform Instagram, Gallagher said: “Thanks everyone for the messages and well wishes.

“Glad it’s not too serious and hopefully be back out there soon.”

There were no signs of injury when Rovers left the field at half time, with Tony Mowbray revealing the details during his post-match press conference.

Gallagher was replaced by Bradley Dack at half time, and Mowbray after the match at the City Ground: “I’m more concerned about Sam Gallagher who has gone to hospital for an X-ray on a potential punctured lung, he was coughing up blood at half time.

“He fell flat on his back, it wasn’t nice to see at half time him coughing up blood, the doctor got involved and he was taken to hospital awaiting an X-ray.”
