Berkman, who hit .293 and hit 24 home runs in 2005, is expected
to recover within 4-6 weeks, said Astros team doctor David Lintner.
The Astros play their first spring training game March 2.
The scar tissue developed as a result of surgery in November
2004 that repaired Berkman's torn anterior cruciate ligament.
Berkman hit .333 with two home runs and 14 RBI in 14 postseason
games last season. The Astros won the National League before losing to the Chicago White Sox in the World Series.
