David Ortiz injury: Red Sox star has ultrasound on Achilles

Boston Red Sox designated hitter David Ortiz had an ultrasound treatment on his Achilles tendon Monday.

"I did it just to make sure," Ortiz said. "I talked to so many people that had it done, so I wanted to be sure. They said they were sore after doing it, but I wasn't sore at all."

Ortiz said the procedure will prevent him from running for the next 4-6 weeks, but it will allow the 36-year-old to have no issues when it's time for his offseason workouts to begin.

"The doctor said I could play right now," he said. "I did it just to make sure everything was ready to go."

Ortiz is expected to be in a boot for the next 7-10 days. The procedure was precautionary, Ortiz said.

The eight-time All-Star played in just 90 games this season. He injured his Achilles in July and made just one start after the injury. He went 2 for 4 in a game in August but was back on the disabled list shortly after the game.

Ortiz, who hit .318 with 23 home runs this season, is scheduled to be a free agent this offseason.
