Milwaukee, WI (Sports Network) - The Milwaukee Brewers placed third baseman Wes Helms on the 15-day disabled list Friday.
Helms slipped on a rubber mat in a tunnel between the clubhouse and dugout at Hiram Bithorn Stadium and injured his right knee while the Brewers were in San Juan on Wednesday playing the Expos.
He will have surgery on Monday.
Helms is in the midst of a five-game hitting streak and has a hit in nine of his last 10 contests. He has raised his average 34 points this month and is batting .302 (16-for-53) with seven RBI during that span.
Helms batted .261 with 23 home runs and 67 RBI in 134 games last season for Milwaukee. He was acquired by the Brewers along with pitcher John Foster on December 16, 2002 in a trade that sent pitcher Ray King to Atlanta.
Last season marked his first as a regular in the starting lineup. He set career marks in nearly every offensive category and became just the second third baseman in franchise history to hit 20 home runs in a season.
The Brewers recalled Corey Hart from Triple-A Indianapolis to fill the roster spot.
