Bradley Dack's season is over after boss Tony Mowbray revealed the League One player of the year has picked up another hamstring injury.

Dack has struggled with hamstring problems during the course of the season season and will undergo a scan today to determine the extent of his latest injury.

The 24-year-old, who has scored 18 goals this season, sat out the 1-0 defeat at Charlton on Saturday and won't be involved against Oxford in Rovers' final league game on Saturday.

Mowbray is hopeful that Dack will be able to return to pre-season training fully fit as Rovers gear up for life back in the Championship.

“His hamstring,” Mowbray said of the reason behind Dack's exclusion

“He’s had a few hamstring issues this season and you can’t mess about with them.

“He has had to come off it fully and he’s due a scan and hopefully it won’t be too severe.

“But he’s out injured and hopefully come back ready for pre-season.”

Dack was one of six players left out by Mowbray, four days after Rovers had secured promotion.

They slipped to a first defeat since February despite an improved second half showing.

Mowbray added: “The players gave their all but some times top players can make that difference.

“For instance, would Bradley have scored and taken one of those opportunities in the second half? Probably, but he’s not available so we have to get on with it.

“It’s part and parcel of football, you’re only as good as the depth of your squad and I felt they showed they have a lot of good qualities. But Charlton are a good side, with some good players, and they dug in and got themselves a result.

“I didn’t feel over-threatened by them but they deserve credit because they got the three points.”

The win kept up Charlton's play-off hopes, while Rovers' title chances took a knock.

Of his new-look side, Mowbray said: “Let’s give Charlton credit, they had an intensity, played on the front foot.

“We came with a game plan not to play our normal game.

“I didn’t think we could with the personnel available, sat in behind the ball and tried to counter-attack with the pace of Samuel and Armstrong.

“That’s not the way we generally play, it was forced by the personnel we had. Then we gambled second half, had a few chances.

“With different personnel we might have taken the chances that came our way.”
