Carlos Santana's recovery from a mild concussion continued Friday afternoon with light cardio work and swings in the indoor cage.

The Indians' catcher is eligible to come off the seven-day concussion disabled list on Saturday, but that will not happen. Santana's to-do list is expected to include catching a bullpen, running the bases and taking batting practice.

"Then he's going to be re-tested," manager Manny Acta said. "After that, we'll wait for approval from Major League Baseball to allow him to play."

There is no timetable for Santana's return.

"We're optimistic that, by next week, he should be back in the lineup," Acta said.

On May 25 against the White Sox in Chicago, Santana absorbed a foul to the mask. He complained of dizziness and exited late in the game.

Two days later, backup Lou Marson was hit in the mouth by an off-speed pitch from White Sox right-hander Gavin Floyd. The contusion required stitches, which were removed Thursday.

Marson missed three games before returning to the lineup Friday night against Minnesota. He batted ninth against Twins right-hander Carl Pavano.
