The Patriots have formally placed Dion Lewis on the PUP list. The running back is in need of a second knee surgery and reportedly will be out for at least another eight or 9 weeks. The PUP list designation sidelines him for the first six weeks of the season. 
The Patriots will also place tackle Sebastian Vollmer on the PUP list, per Adam Schefter of ESPN.com (on Twitter). Theoretically, New England can bring him back, but it’s more likely that he will not play this year due to his nagging hip problems.
Lewis’ injury does not involve the ACL or any other ligaments, which is good news for his recovery. Lewis was a key cog of New England’s offense before his ACL tear, rushing 49 times for 234 yards and catching 36 passes for 388 yards. He also scored four total touchdowns, two through the air and two on the ground.
Vollmer, when healthy, has been a mainstay at tackle for New England since 2009. However, Pro Football Focus (subscription required) ranked Vollmer as the 42nd-best tackle out of 77 qualified players last season, and he was thought to be on the roster bubble earlier this year. His contract is set to expire at the end of the 2016 campaign and earlier this offseason Patriots passed on discussing an extension with him as a result of his injury issues.
In related news, the Patriots cut linebacker Ramon Humber, tight end Steven Scheu, and offensive tackle Keavon Milton.
