CLEVELAND -- Minnesota Twins first baseman Joe Mauer missed his fourth straight game with lower back spasms and manager Ron Gardenhire said the six-time All-Star could go on the disabled list.

Mauer played catch and hit off a batting tee Wednesday, but it's unclear when he'll be able to play.

The Twins have been playing short-handed throughout their four-game series with the Indians and their lack of depth became a bigger problem when outfielder Sam Fuld couldn't play Thursday because of headaches. Gardenhire said Fuld was being checked for a possible concussion.

The injuries left infielder Pedro Florimon as Minnesota's only player on the bench.

Eduardo Escobar, normally a shortstop, had to play left field Wednesday. He misjudged a fly ball in the ninth inning that led to Cleveland scoring the winning run in a 4-3 loss. Escobar started in center Thursday.
