FOXBORO -- Patriots running back Dion Lewis had a complication after his ACL surgery and needs to have a second procedure, according to a source. The nature of the procedure isn't specifically known, but it doesn't involve the ACL or any other ligaments.
Depending upon when he has the procedure, it should be about 8-10 weeks before he can begin training, which means he will begin the season on the physically unable to perform list.
Lewis tore the ACL in a game against the Washington Redskins last November. He appeared at one OTA practice in the spring but was on the PUP list in camp and hadn't practiced.
He was enjoying a breakout season before he got hurt, averaging 4.8 yards per carry, with 36 catches and four touchdowns. His ability to operate in space gave the Patriots another dimension on offense.
