MINNEAPOLIS -- It remains unclear how much time Indians center fielder Grady Sizemore will miss due to his latest right knee injury.
On Tuesday, Sizemore underwent an MRI exam in Cleveland to evaluate the extent of the injury that sent him to the 15-day disabled list one day earlier. Indians manager Manny Acta said the results did not initially reveal any signs of serious damage.
"There's not much I can say," Acta said, "other than he had the MRI, and it doesn't appear to be anything as serious as we might've feared. ... For now, there's no timetable. Hopefully, we can have him as soon as possible."
Acta indicated that Indians head athletic trainer Lonnie Soloff, who is currently in Cleveland with Sizemore, would be able to provide a more detailed update later this week.
Sizemore injured his knee -- not the surgically-repaired left knee that plagued him last season -- while rounding first base in the first inning of Sunday's 8-3 loss to the Orioles. Cleveland described the center fielder's ailment as a bone bruise, which is the same injury that sidelined him for two weeks earlier this season.
For the time being, rookie outfielder Ezequiel Carrera is filling in as the Indians' regular center fielder. It is a chance for Carrera to show Cleveland if he can continue the success he was having with Triple-A Columbus.
In 81 games for the Clippers, Carrera hit .288 with two home runs, eight doubles, three triples, 25 RBIs, 35 stolen bases and 63 runs scored. He posted a .373 on-base percentage and collected 94 hits.
"I feel bad about what happened to Sizemore," Carrera said. "He's a good guy. For me, I wanted the opportunity to play center field. I want the confidence of the manager and the team. I want to do my job, and make the team happy with how I play."
