Jimmy Rollins' strained right groin suffered Sunday is apparently severe enough that it will require a trip to the disabled list for the Phillies shortstop.

That's straight from the man himself, who took to Twitter on Monday to announce the news.

"Soooooo this is what we got...mild grade 2 strain. DL," Rollins tweeted. He followed up with another: "Gone till September........."

Phillies general manager Ruben Amaro Jr. later announced that Rollins has been placed on the 15-day disabled list. To fill Rollins' spot on the 25-man roster, the club activated third baseman Placido Polanco from the disabled list.

Rollins, 32, is hitting .268 this season with 22 doubles, 14 HR, 58 RBI, 79 runs and 28 stolen bases. He has appeared in 121 of the Phillies’ 125 games while committing five errors in 504 total chances (.990 fielding percentage).

Polanco, 35, was originally placed on the DL with a sports hernia on August 16 (retroactive to August 7). In 89 games this season, the 2011 National League All-Star is batting .275 with 40 RBI and 35 runs while posting a .976 fielding percentage, second-best among all NL third basemen. Polanco previously missed 19 games this season while on the disabled list with lower back inflammation (July 5-30).
