ARLINGTON, Texas (Reuters) - Texas Rangers All-Star Josh Hamilton sat out his team's 6-5 loss to the Minnesota Twins Sunday and will miss extended time with a rib injury.

Major League Baseball does not have a disabled list during the month of September but Hamilton will be out of the lineup for an undetermined amount of time after slamming into the wall while making a catch Saturday against the Twins.

"It's not good. All signs point to not soon," Hamilton told the team's website (texas.rangers.mlb.com) in regards to his timetable for return. "I feel like I have been in a car wreck."

Hamilton is enjoying the best year of his career and is leading the American League with a .361 batting average while hitting 31 home runs and driving in 97 runs.

The absence of slugger Hamilton leaves a sizeable hole, however.

"The last time it happened I felt a lot better after a week," said Hamilton, who had a similar injury in 2009 when he missed 13 games. "So we'll see."
