We knew Ray Allen was scheduled to undergo ankle surgery Wednesday, and the Celtics made it an and-one with Mickael Pietrus (right knee) undergoing surgery as well. The Celtics sent out a press release saying both surgeries were successful, as it seems all surgeries are.

Here’s the press release from Celtics.com, in case you want to read three mostly-meaningless paragraphs:

The Boston Celtics announced today that guard Ray Allen and guard/forward Mickael Pietrus both underwent successful surgery at New England Baptist Hospital this morning. Both surgeries were completed by Celtics Team Physician Dr. Brian McKeon and were assisted by Dr. Mark Slovenkai.

Allen, who had successful arthroscopic surgery on his right ankle, averaged 14.2 points, 3.1 rebounds, 2.4 assists and 1.07 steals in 34.0 minutes per game for the Celtics during the regular season. He also shot 45.3 percent from 3-point range, which ranked fourth in all of the NBA this past season and was a career high, besting his previous career high that was set during the 2010-11 season (44.4 percent).

Pietrus, who had successful arthroscopic surgery on his right knee, averaged 6.9 points and 3.1 rebounds in 21.9 minutes per game for the Celtics during the regular season. He also finished third on the team in three-point field goals with 61 behind Allen (106) and Paul Pierce (100). Pietrus scored a season-high 16 points against Oklahoma City on February 22.
