"About a month from today, Jamey Carroll will turn 38 years old. That will make the veteran infielder, signed by the Twins earlier this offseason to man shortstop over the next couple seasons, the same age as former Minnesota third baseman Corey Koskie.

Of course, while Carroll is enjoying the best years of his pro baseball career, Koskie has been out of the game since 2006, when a concussion sustained in Milwaukee ended his days as a major-leaguer.

An athletic baseball player with a tremendous passion for the game, cut down in his prime by an injury that seemed totally harmless at the time, even to him. I brought up the unfortunate parallel between Koskie and Justin Morneau after the latter had been sidelined for a month by a concussion suffered in 2010, and unfortunately, little has happened since then to dispel such allusions.

In the weeks and months following Morneau's initial incident, Twins trainers repeatedly talked about the "progress" he was making toward getting back on the field. He never returned in 2010, but embarked on an offseason program designed to get him back into playing shape while protecting his head. Again, "progress" was the go-to buzzword in all Morneau updates."
