Wright was placed on the 15-day DL for the second time in three weeks on Wednesday by the Cleveland Indians, who can't seem to get a player healthy without another breaking down.
Indians general manager John Hart said the 24-year-old Wright, who was on the DL for two weeks in May and twice last season, has fluid in his shoulder that is causing pain.
"We're going to have Jaret shut it down for a week to 10 days and hope that the fluid goes out and then give it a try," Hart said.
Wright's injury is yet another setback for the right-hander whose career seemed so promising when he won two playoff and a World Series game as a rookie in 1997.
The Indians currently have eight players _ six pitchers _ on the DL and have had to make 28 roster moves since May 18.
An MRI revealed that Wright, who as a rookie in 1997 beat the New York Yankees twice in the playoffs and Florida in Game 4 of the Series, has a shoulder injury, but that his rotator cuff is sound, Hart said.
"Surgery has not been brought up at this point," Hart said. "No one is saying that this will require surgery."
Wright, who is 3-4 with a 4.70 ERA in nine starts, was out from May 12-27 with tightness in his shoulder. He was 0-2 with a 16.50 ERA since being activated and complained of soreness during a June 2 start in St. Louis.
He was out last year with a pulled muscle in his upper back and strained muscle in his shoulder.
Hart said Wright's current shoulder problems are not related to the ones he suffered last year and contributed to his dreadful season.
Wright went 8-10 with a 6.06 ERA in 1999. He was also accused of throwing at batter's heads and was called into then-AL president Gene Budig's office in New York to discuss his conduct on the mound.
The Indians were counting on Wright to have a big 2000 season, and can hardly afford to have another pitcher sidelined.
Right-hander Paul Rigdon was activated from the DL and started for the Indians on Wednesday night in Milwaukee. He lasted just 26 pitches but Cleveland went on to win 9-5.
In his major league debut on May 21, Rigdon pitched seven shutout innings to beat the New York Yankees. But before he could make his second start, Rigdon, 24, sustained a pulled a muscle in his rib cage while throwing in the bullpen on May 26 and went on the DL.
Reliever Ricardo Rincon underwent surgery on spurs in his left elbow Wednesday in Birmingham, Ala., and will be out until mid to late-August, Hart said.
Set-up man Paul Shuey, who had surgery on his hip in San Francisco last week, has begun throwing and could be back in early July.
Starter Charles Nagy has begun playing catch following surgery to remove bone chips from his elbow and is progressing ahead of schedule.
And All-Star right fielder Manny Ramirez, who with a strained hamstring, is taking batting practice and should come off the DL on June 14.
