The injury struggles that Tony Romo has endured over the past few seasons can be summed up in one word: frustrating.

Romo was limited to just four games last season because of a broken collarbone, and he might miss 10 more this year because of a broken bone in his back. ​

Yesterday Romo received some sage advice from someone who knows a thing or two about career-altering injuries: Redskins legend Joe Theismann.

That's right. Romo should retire.

After last couple of seasons, it'd be hard to blame Romo for listening to Theismann, who experienced his fair share of pain during his playing days. The injury he suffered last week is especially scary, because it involves the spine. If Romo were to return to the field and get re-injured in that same area, who knows what long-term effects it could have on him?

Romo also has to ask himself what he has left to prove on the football field. The 36-year-old has already made close to $120 million in his career, so you would hope he has enough money put away to support himself and his family for the rest of his life. He's also found a lot of success on the field, working his way up from an undrafted free agent to being the starting quarterback for the most famous franchise in the NFL. Sure, Romo never made it to the Super Bowl or found a whole lot of success in the postseason, but that's honestly nothing to hang his head about. Winning in the NFL takes some luck, and the Cowboys have certainly been on the short end of that stick more than a few times. 

If rookie Dak Prescott continues to play well into the regular season, and the Cowboys are winning games, it might be best for both parties if Romo calls it a career. A situation like that would be kind of poetic, when you consider how Romo began his NFL career.
