Tampa Bay Rays designated hitter Luke Scott took a few steps forward Monday morning in the clubhouse while discussing the left hamstring he injured during Sunday's game.

They were normal steps.

Then, Scott stiffened his left leg and took a few steps.

"If I pulled my hamstring I would walk like this," he said. "I've pulled hamstrings before. This is just tight."

"He's fine," Rays manager Joe Maddon said a few hours later before the Rays 5-1 loss to the Boston Red Sox at jetBlue Park. "There's no real concern."

Yet, given his history of hamstring issues, that Scott had to leave a game with a tight hamstring sustained while running out a fly ball has caught the Rays attention.

Also, Scott is coming off an injury plagued 2012 season that saw him head to the disabled list once with an oblique strain and again because of back stiffness. Both were not believed to be serious as the time Scott was injured.

"I'm not concerned yet," Maddon said. "Tightness and a pull are two different things, so we'll just wait and see."

Scott will not play today in Fort Myers against the Minnesota Twins. Wednesday is an off day. It's unlikely he will return Thursday because the Rays play the Pittsburgh Pirates in Bradenton. So, it's likely Scott won't return until Friday when the Rays play the visiting Philadelphia Phillies.

"I have no idea," Scott said when asked when he will return, "but it shouldn't be long."

This will create at-bats for a number of players who could fill the void in Scott's absence, namely Jack Cust, Shelly Duncan and Leslie Anderson.

"The depth is there," Maddon said.
