Rashford has been battling with a shoulder injury for quite a long time and has planned to go for a surgery that would keep him on the sidelines for about 12 weeks.
After conversations between Rashford, Ole Gunnar Solskjaer and club staff it has been concluded that the only best option for the 23-year-old is to go under the knife.
"Everyone has an opinion but no one knows my body better than me.
"I have read some call me selfish for holding off getting the surgery this season but it was never about putting myself first and that's how we've reached this point, and something as a 23-year-old I have had to learn the hard way.
"To guarantee I can play this game as long as possible I need to listen to my body. When I step on the pitch I always give 100%. Physically my 100% just wasn't possible.
"I'm walking away from last season with 36 goal contributions, but more importantly I'm walking away with lessons learnt."
Rashford was part of the England squad that missed out on the Euro 2020 title to Italy in the final, and being among the players who missed in the penalty shoot-out, Rashford explained how it feels to represent his country.
"It is hard to describe the feeling of representing your country. Given the choice no one would ever turn that down at such a big tournament. As a little boy or girl you dream of those moments.
"I had been deemed fit for the full season, and given my injuries were being managed, what was another couple of weeks? Managing the pain I was training well and found a lot of comfort in the England camp after the Europa League final.
"In hindsight, if I had known I wouldn't have played a significant role in the Euros, would I have gone? Hindsight is a wonderful thing isn't it?
"I didn't want to let anyone down but ultimately looking at some of my performances towards the end of last season I felt like I was."
