Cowboys MLB Sean Lee underwent surgery on his torn left ACL Thursday.

Doctors also repaired a "small meniscus tear." According to coach Jason Garrett, the Cowboys have yet to decide if Lee will begin training camp on injured reserve or the active/PUP list. Either way, Lee is facing long odds of making a Melvin Ingram-esque return late this season.

Coach Jason Garrett revealed MLB Sean Lee (knee) will undergo surgery to repair his torn ACL on Thursday.

Some are holding out hope that Lee can make a Melvin Ingram-like return to the lineup in December. Ingram tore his ACL around the same time last year and played the final four regular season games and in the playoffs. ESPN Dallas isn't taking the bait, and expects Lee to miss the entire year. Justin Durant has been running with the ones at MIKE 'backer. Rookie Anthony Hitchens is also in the mix.

ESPN Dallas doesn't expect Sean Lee (ACL surgery) to return this season.

There's been some thought that Lee could be stashed on short-term I.R. in hopes of making a late-season impact, but the Cowboys aren't going to rush back a player with his injury history. Lee is facing a 8-12 month recovery timetable and should spend the entire 2014 season on injured reserve.

Cowboys ILB Sean Lee will get a second opinion on his torn left ACL, but will likely undergo surgery in 2-3 weeks.

CBS' Jason La Canfora confirms Lee is dealing with "no other ligament issues." We'd be shocked if the second opinion did anything other than confirm Lee's initial diagnosis.

Chargers OLB Melvin Ingram returned from a 2013 ACL tear suffered on May 14 to play in San Diego's final four regular season games.

Ingram also contributed in the playoffs, starting twice and compiling six tackles to go with an interception. Cowboys MLB Sean Lee's ACL tear occurred on May 27, so he's just two weeks behind Ingram. Dallas has yet to place Lee on injured reserve, perhaps in hopes of a late-season impact. The Cowboys would have to stash Lee either on the reserve/PUP list or I.R./designated for return.

The Cowboys see Sean Lee's rehab as an 8-12 month process.

Although Lee did not sustain any other ligament damage Tuesday outside of his torn left ACL, he will miss the entire 2013 season. The only silver lining is that he should be truly ready for the 2015 season, unlike recent players that rushed back too quickly from their tears (Robert Griffin III). IDP owners need to get fourth-round rookie Anthony Hitchens on their radar.

Cowboys ILB Sean Lee has been diagnosed with a torn left ACL, and is expected to miss the entire 2014 season.

The poor just got poorer on defense. Had Lee's (latest) injury occurred a month or two earlier in the offseason, he might have been a candidate for injured reserve/designated to return, but there's little reason to believe that will be the case now. It's the second ACL tear of Lee's career, though the first came to his right knee at Penn State. Lee missed significant time the past two seasons with toe, neck and hamstring issues, and has rarely been healthy since high school. He's an All-Pro talent with third-team injury luck. The Cowboys could be forced to turn to fourth-round rookie Anthony Hitchens in Lee's absence. A defense that was the worst in the league last season could be even worse in 2014. Jerry Jones' cap mismanagement has led to an embarrassing lack of depth.

The Dallas Morning News reports the Cowboys believe ILB Sean Lee has a torn ACL.

That's what has been widely speculated, but the Cowboys won't know for sure until they get back Lee's MRI. Lee got his left knee hung up getting pancaked by first-round OG Zack Martin in a "non-contact" drill. Video of the incident certainly made it look like contact was permitted. Among his many, many other injuries, Lee tore his right ACL at Penn State.
