Andre Blake underwent a successful menisectomy and will miss four to six weeks, according to the club. A menisectomy is a surgery usually used to repair a partially torn meniscus (the cartilage between the thigh and shin), according to this National Institute of Health web page.
The twenty-four year old Blake had only played a limited amount in the Union's preseason camp, with the lion's share of minutes going to new signing John McCarthy. Prior to this however, Blake led the Jamaica National Team to a berth in the 2015 CONCACAF Gold Cup tournament in July thanks to his Golden Gloves winning performance in the 2015 Caribbean Cup. During that tournament, Blake was a wall, being the difference-maker that saw the Reggae Boyz beat Trinidad and Tobago in penalties.
Blake should resume his duties sometime near the end of March or beginning of April. There's been speculation that Blake would be loaned out this season much like Zac MacMath, however with this injury it might be more of a rehab stint with a lower division club than with another MLS club.
