DENVER -- Brewers infielder Tony Graffanino has a torn anterior cruciate ligament and a torn meniscus in his right knee, and his 2007 season is over.
Graffanino suffered the injury making a leaping catch to end the first inning of Wednesday's 19-4 loss at Colorado, capping a three-game Rockies sweep in which the Brewers were outscored, 36-10. He traveled back to Milwaukee after the game and underwent an MRI scan on Thursday that revealed the extent of the injury.
Graffanino will undergo surgery as soon as his swelling subsides, according to a team spokesman.
The Brewers will recall second baseman Rickie Weeks from Triple-A Nashville to take Graffanino's roster spot, and Weeks should be in uniform for the start of a three game series in Houston on Friday. The Brewers had an off-day Thursday and entered the day with a one-game lead in the National League Central over the Cubs.
Weeks, optioned to Nashville on Aug. 1 to work out of a prolonged slump, appeared in six games there and batted .455 (10-for-22) with three doubles and a triple. He was hitting .212 with five home runs and 19 RBIs in the Majors and went 2-for-20 (.100) on a road trip in Cincinnati and St. Louis just before he was sent down.
The loss of Graffanino represents a significant blow to the Brewers' depth because he appeared at all four infield positions this season, and also started three games in left field. The 35-year-old was playing on a one-year, $3.25 million contract he signed in January and batted .238 with a career-high nine home runs in 231 at-bats.
"He's obviously a big part of this team," said fellow veteran utility man Craig Counsell.
Graffanino has suffered knee injuries before. He tore the same right ACL in 2002 and was on the disabled list from Aug. 25 through the end of the season. Graffanino underwent surgery on Sept. 9 of that year.
He also injured his left knee in 2004, first going on the DL from May 1-27 with a torn meniscus, then returning to the DL on Aug. 3 with a torn posterior cruciate ligament, again missing the remainder of the season.
