Ellison suffered a torn patellar tendon in Week 17, leaving him uncertain for the start of the 2017 season. He's been useful to the Vikings as a blocker, but with just 42 receptions in 58 career appearances, Ellison has never emerged as a key part of the passing game.
Exum (ribs) has been placed on injured reserve, Chris Tomasson of the St. Paul Pioneer Press reports.
The Vikings have dealt with a ridiculous string of injuries at the safety position over the past few weeks, allowing Exum to make a couple of starts. The team is now left with Harrison Smith (knee/hamstring), Robert Blanton (knee), Andrew Sendejo (knee) and newly-signed Anthony Harris.
Joseph (foot) will have toe surgery during the offseason, Chris Tomasson of the St. Paul Pioneer Press reports
This shouldn't come as any surprise, given that Joseph dealt with a foot injury throughout the entire second half of the season. He missed Weeks 12-16, but with 56 tackles in just 12 games, Joseph cemented his reputation as one of the league's better run-stopping interior linemen. He only has 12.5 sacks in 81 career games.
Levy (hip) participated in the the Lions' first set of offseason workouts, which began on Monday, the Detroit Free Press reports.
It's unclear if Levy, who played just 16 snaps last year, will be cleared to take part in football drills next month, on the plus side, the linebacker -- who racked up an IDP-friendy 151 tackles in 2014 -- maintains that his recovery from surgery to repair a torn labrum in his hip has been "going great."
Pettigrew (knee) was placed on injured reserve Tuesday, Tim Twentyman of the Lions' official site reports.
After Pettigrew sustained a torn ACL Sunday at St. Louis, the move is merely a bookkeeping measure by the Lions intended to open up a spot on the 53-man roster. The organization will use it to sign a tight end, Bear Pascoe, who is known for his blocking.
Quin underwent surgery this offseason to clean out bone chips in his ankle but expects to be ready for the start of the Lions' offseason program, the Detroit Free Press reports. "I did my surgery, my ankle didn't swell very much," he said. "I was back a lot earlier just from my standpoint than I was last time. Obviously, we'll see what the trainers say and allow me to do when I get back, but it feels a lot better this year than it felt in 2014 when I had it done the first time."
Speaking of "last time," Quin had ligaments repaired in the same ankle after the 2013 season and proceeded to miss the majority of spring workouts during that offseason. Because the procedure was less intrusive this time around, he's confident that the Lions' training staff will clear the cornerback to take part in the initial voluntary workouts next week. Once the fall rolls around, he'll be looking to repeat his 2014 campaign in which he led the NFL with seven interceptions and earned the sole Pro Bowl bid of his career.
Zenner (chest) could experience an uptick in usage next season, Tim Twentyman of the Lions' official site reports.
The release of Joique Bell on Tuesday whittled down the Lions' backfield situation to Ameer Abdullah, Theo Riddick, and Zenner. Assuming the status quo remains after free agency and the draft, Abdullah seems to be the leader in the clubhouse for the top gig, but Riddick's pass-catching prowess leave the door open for the versatile Zenner to have a regular role in the offense. In the preseason, Zenner led all players with 183 rushing yards, and he followed it up with 17 carries for 60 yards and two catches for 11 yards in six regular season contests before his rookie campaign ended when he sustained cracked ribs and a partially collapsed lung in Week 6.
