Troy Tulowitzki is again dealing with a lower body injury

Troy Tulowitzki insists he won't ask for a trade from the Colorado Rockies, but he might be making a trip soon anyways.

A trip back to the disabled list that is, after he was forced to leave Friday's game in Los Angeles with tightness in his left quadriceps.

The injury doesn't seem to be overly concerning based on the early information from the Rockies. They're currently listing him as day-to-day, but given Tulowitzki's history of leg issues there's no good news until there's actually good news.

In the past, he's missed significant time with similar quad injuries and an ailment that was once described as heavy legs. But that's not all.

In 2012, he underwent season-ending groin surgery in June for an unusual condition called hockey goalie/baseball pitcher syndrome. Apparently, Tulowitzki suffered multiple tears in his groin leading up to the diagnosis, which led to the muscle fibers folding inward and becoming entrapped as the torn layer heals.

That does not sound pleasant.

In 2014, Tulowitzki underwent season-ending hip surgery in August after struggling to stay on the field. That left many wondering how Tulowitzki's body would respond this season. He's been granted a handful of days off as precaution, but seemed to be holding up well physically until Friday.

His production hasn't been inspiring, however. Through 32 games, he's hitting .284/.292/.448 with just two home runs and 11 RBIs. Combined with Carlos Gonzalez's season long struggles, it's no wonder Colorado has lost 12 of its last 13.

If there's good news, it's the latest injury isn't directly related to his surgically repaired hip. The bad news, well, that's everything else, but especially the timing.

Though all parties say no trade is imminent — Rockies general manager Jeff Bridach even called the recent trade drama a "media production" — Tulowitzki's trade value takes a small dip every time he limps off the field, and sooner or later the injury risks coupled with age will outweigh the rewards of a difference-making shortstop in his prime.

And no, this isn't just Tulowitzki's way of getting out of the lineup. He knows the consequences of not playing. He knows what it does to his trade value and he knows each game missed keeps him in Colorado that much longer.

He simply can't stay healthy, which makes the Rockies unwillingness to part with some or all of the $110 million remaining on his contract all the more puzzling. The longer they wait, the less flexibility they'll have to maneuver a deal or begin the rebuild they so desperately need.
