Tim Lincecum says his back was feeling better Thursday than it did when he was forced to leave Game 2 of the World Series on Wednesday night.

"Sitting on the plane was a little iffy but I just did my best to stay stretched out and keep loose," Lincecum said. "And now I'm just going to get it treated and see how it feels."

Lincecum underwent an MRI and the results showed no structural damage.

The right-hander is expected to be available for the remainder of the series.
