More than likely, the Green Bay Packers are going to go into Week 1 of the regular season with only four outside linebackers on the roster.

Veterans Clay Matthews and Nick Perry will start, with Reggie Gilbert as the top backup and Kyler Fackrell serving as the fourth option.

It’s possible, maybe even likely, that the Packers will use combinations of fronts to masked the depth issues at outside linebacker. Defensive coordinator Mike Pettine could use more four-man fronts, but even then, the Packers only kept five defensive linemen on the roster.

If the Packers do eventually dip into the free-agent pool for help at edge rusher, here are six potential options:

John Simon

The Indianapolis Colts couldn’t find a fit for Simon in their new defense. The Packers wouldn’t have any trouble. Simon is an experienced outside linebacker who can rush, set the edge and play some coverage. He made a bunch of plays for the Houston Texans and Colts over the last two years and is one of the better veterans players still available. Like Ahmad Brooks last season, Simon would make an ideal third or fourth option on the edge.

Nate Orchard

The former second-round pick was underwhelming in Cleveland, largely due to injury. He produced a standout preseason this summer but couldn’t find a spot on a talented Browns defensive line. When healthy, Orchard can beat blocks and disrupt the pocket, and he’s still only 25.

Jayrone Elliott

The former Packer put together a big preseason but wasn’t able to crack the Saints roster. The flashes of brilliance were always there for Elliott, but the consistency never developed, so former Packers GM Ted Thompson shipped him to Dallas at cutdowns last year. At the very least, Elliott would provide a known commodity with some possible untapped potential rushing the quarterback.

Steven Means

Khalil Mack’s former teammate at Buffalo was one of the stars of the preseason. Mean is 27 and has only two career regular-season sacks, but it’s certainly possible he’s a late bloomer. While the Eagles were too deep at defensive end for Means to stick, he’d provide valuable experience and pass-rushing ability for the Packers’ edge group.

Brian Robison

Robison is 35 and coming off his least productive season sacking the quarterback (four) since 2010, but he could give Pettine an experienced pass-rushing option at defensive end in a potential four-man front. Playing outside linebacker would be foreign, but Pettine could make it work. Like so many veterans this time of year, Robison got pushed out of Minnesota by a couple of young defensive ends Mike Zimmer likes, but that doesn’t mean he can’t play.

Tyrone Holmes

Holmes is a terrific athlete, especially for his size. He was all over the field during the Chiefs’ preseason finale win over the Packers. Ask Tim Boyle about him; he saw plenty of Holmes in Kansas City. The former Montana star led the FCS in sacks in 2015. He needs technical work, but the physical tools are all there.
