Shaq 2nd half of the season debut-April 1?

 The Boston Celtics are going to need to make some room on the bench pretty soon -- enough room for a 7-1, 325-pound gentleman named Shaquille O'Neal.
A team source told ESPN Boston on Wednesday that everything is looking good for O'Neal to return to the team on April 1 after suffering from a problem with his right Achilles that has kept him out for 22 games.
Celtics coach Doc Rivers doesn't seem to be paying too close attention: "[Shaq] is coming back soon enough," said Rivers, according to the site. "I don't know what the date is, if it's in the next four or five days or anything like that."
In the 36 games he has played this season, O'Neal has averaged 20.7 minutes, 9.3 points, 4.9 rebounds and 1.2 blocks.
