It looks like Micah Parsons is set to become a full-time defensive end.

This upcoming season, Parsons will make the full switch from outside linebacker to defensive end. Parsons will not be participating in the Cowboys’ offseason program, and instead he will work out in Austin to bulk up in preparation of the position change, as first reported by Cowboys writer Clarence Hill Jr.

Parsons took to Twitter to respond to people who were critical of his intention to bulk up.

His tweet indicates that he only plans to gain roughly six to nine pounds and won’t weigh more than 255 at any point of his career. This small increase in weight will allow him to continue to pass the rusher with speed, which is what makes him such a special player.

Parsons never fit the role of a traditional linebacker, as he is used primarily as a pass rusher and rarely in coverage. Last season, he recorded 13.5 sacks, which was the seventh-highest mark in the NFL and ranked third among linebackers. He even earned first-team All-Pro honors as an edge rusher last year due to his prowess off the edge.

There are two seasons left on Parsons’ contract with the Cowboys. The change to defensive end will play a big factor in his future contract, as the new position typically commands more money than linebackers.

You can catch Parsons in action in his new position when the NFL preseason kicks off in August.
