Middlesbrough: Seb Hines set to undergo surgery on fractured knee
Middlesbrough centre-half Seb Hines has been told he must have an operation to repair his fractured knee, ruling him out of action until September.
The 24-year-old has been a regular for Boro in the past two seasons, making 27 appearances in each campaign.
"He's a strong lad with good mentality so will come through it fine," Boro manager Tony Mowbray told BBC Tees.
"He's been a warrior for us and played through discomfort at times. We wish him a speedy recovery."
Meanwhile, Mowbray has heaped praise on veteran midfielder Julio Arca, who was released by the club this week.
Arca has suffered from a long-standing toe injury and with his contract set to expire at the end of the season, was allowed to return to his native Argentina early.
"Julio has been a model pro for us," Mowbray added.
"He's very conscientious, has good habits and has been a good role model for the younger players.
"The last year has been difficult for him with his toe but he comes in and works hard every day - we wish him well."
