Ortiz to miss a week with Achilles injury

 Boston Red Sox designated hitter David Ortiz is expected to miss at least one week with an injury to his right Achilles tendon.

"The MRI has shown there's not a tear, he's sore and he's going to get another opinion," said Sox manager Bobby Valentine in Tuesday's pre-game press conference. "I talked with some of the medical staff, they thought the 24-hour wait at least is something that gives you a different opinion sometimes. We'll wait at least the 24 hours and probably into tomorrow maybe until we get a second opinion."

Ortiz suffered the injury during Monday's 5-1 victory over the White Sox while stepping on second base after Adrian Gonzalez hit a three-run homer. He has been placed in a walking boot as a precaution.
