While the Phils prep to play their second game of a seven-game road trip in Milwaukee, Chase Utley remains in Philly.

Utley will have an ImPACT test on Saturday, which will test the severity of the concussion he suffered when he was hit by an Eric O'Flaherty pitch on the side of his helmet on Wednesday night at Citizens Bank Park.

Although GM Ruben Amaro Jr. initially said he thought it was a "very, very mild" concussion, the Phils clarified Friday that they won't know the severity until they get results from the ImPACT test.

In addition they said Utley has not experienced headaches on the night of or in the days since the injury.

A report on CSNPhilly.com earlier today said Utley might not rejoin the Phillies until next weekend, when they start a four-game series with St. Louis at Citizens Bank Park.

Since the Phils enter Friday with a magic number of 4 to make the playoffs and 11 to wrap up both the division and home field throughout the playoffs, there is obviously no need to rush a concussed player back onto the field.
