Down Goes Aramis Ramirez

Hold your breath, Cubs fans. Aramis Ramirez dislocated his left shoulder diving for a grounder in Friday night's game against the Brewers. We'll have to wait and see what the full prognosis is, but this could be a very serious blow for Chicago depending on the type of dislocation.

Ramirez, who came into the game batting .369 with 16 RBI, injured the shoulder when he made a great diving stop on a sharply hit grounder off the bat of Ryan Braun. He immediately grabbed his left arm in pain and Braun was safe at first as the ball rolled away.

There's currently no timetable for his return, which could vary anywhere from weeks to months. If it's just a partial dislocation similar to the one Hanley Ramiez suffered in 2007, then Aramis could make it back fairly soon and postpone arthroscopic surgery. On the other side of the spectrum, Rafael Furcal missed six months in 2001 due to a complete dislocation.

The Cubs will have to make some key position changes in Ramirez's absence. On Friday night, Mike Fontenot shifted from second base to third while Aaron Miles came in to play second. That kind of arrangement moving forward would put a major dent in the Cubs' offensive potential.
