Breaking news: Kevin Durant to miss remainder of 2014-2015 season due to "regression" in recovery for broken foot (Update)

(Update: Sam Presti statement below)

Kevin Durant's follow-up season to his historic MVP campaign is over.

Thunder GM Sam Presti released a statement today announcing that Durant will have a bone graft surgery on his right foot and will miss the remainder of the 2014-15 season.

According to Presti, Durant has experienced a "regression" in his foot:

Durant's initial fracture was showing signs of "regression" and will undergo a bone graft procedure. Will return to basketball in 4-6 months

Durant's procedure is scheduled for next week.

Durant is the first reigning MVP in NBA history since Bill Walton in 1978 to essentially miss his follow-up campaign due to injury.

From ESPN:

Durant underwent surgery Feb. 23 to attempt to alleviate soreness and discomfort in his right foot that was being caused by a screw inserted in October during a procedure to repair a Jones fracture. After the second procedure, Durant was re-evaluated after a week, then re-evaluated again after another week, at which point coach Scott Brooks updated the player's timetable to a "week or two."

Durant had intensified his on-court workouts before being removed from basketball activities last week, even returning to participate in parts of practice, including some 3-on-3. But the soreness that plagued him before the All-Star break and pushed him toward the second surgery was not resolved.

Update: here is the full statement from Sam Presti:

"As we communicated last week, Kevin was going to use this time to engage in consultation and evaluation regarding the persistent soreness in his right foot at this stage of his rehabilitation. As part of this process, Kevin and Thunder personnel traveled to two additional specialists this past week; Dr. Martin O’Malley in New York City and Dr. James Nunley at Duke University. These in-person consults were designed to further supplement the previous evaluations of Dr. Bob Anderson. 

Several conference calls and discussions amongst the specialist team concluded that, while the majority of the soreness in Kevin’s foot was related to continued inflammation of the cuboid bone and would subside with rest, the evaluation process also determined that the Jones fracture of the fifth metatarsal, which had shown significant healing previously, was now demonstrating signs of regression.

With the focus of this process being aimed entirely on Kevin’s long term health and stability, it was the consensus of the specialists team, in addition to a collective decision by Kevin, his representation and the Thunder, that to address the setback of the fracture site, a bone graft procedure would be the most proactive and recommended approach. The bone graft is the standard procedure for the five to eight percent of Jones fracture surgeries that do not initially have success or experience setbacks sometime within the recovery period. While everyone is disappointed that Kevin falls into that group, we are encouraged that the bone graft procedure has historically demonstrated long-term health and stability.

Dr. O’Malley will perform the bone graft surgery early next week in New York. He has extensive bone grafting experience amongst athletes and has been consulting on the case throughout. Kevin will miss the remainder of the 2014-15 season and is expected to return to basketball activities in the next four to six months."
