The Red Sox just can't seem to get healthy.

Just two days after going 2-3 with a pair of doubles, Mike Cameron sat out last night's game against the Athletics with abdominal soreness. While this would seem to be no surprise--Cameron has spent most of the season on the disabled list with an abdominal tear--the soreness is, bafflingly enough, on the opposite side of his body this time around.

Per a Scott Lauber Tweet, an MRI showed that Cameron's old injury has, indeed, been healing. But with his pain having returned, the Red Sox will have a specialist take another look at the new pain today. With Jacoby Ellsbury's cracked ribs still keeping him off the field, the Sox can hardly afford another prolonged injury in the outfield.
