Joe Wright looks set to miss most of the rest of the regular season after rupturing ligaments in an ankle during training.
The centre-back had just worked his way back to fitness after injuring the ankle, with a consultant advising surgery was required after further scans.
Rovers boss Grant McCann said: “He had a 50-50 tackle on Friday, leading into the game. It was another freak accident on the training ground again where he's gone for a 50-50, he's opened up his ankle when it wasn't ready for it and it's opened up the ligaments.
“He trained the next day and was available for the game on Sunday, but was feeling a bit of pain in it so we got it checked out and there it is. He came in on Monday and went for a scan and he's ruptured his ligaments in the ankle.”
Wright was on the bench for Sunday’s Emirates FA Cup game against Crystal Palace, but did not come on. He recently signed a contract extension after an impressive opening half to the campaign.
McCann added: “We're looking at eight to 10 weeks which will be close to the end of the season. By the time he gets back to fitness, there won't be many games left. It's a big blow for us."
