Arizona Wildcats freshman forward Grant Jerrett will not play against Stanford tonight because of foot pain, the first UA player to miss a game this season because of injury.

Jerrett had what Arizona coach Sean Miller called “a little bit of foot pain” after the Wildcats’ win at Washington State last Saturday, and Jerrett missed practices this week while wearing a protective boot.

UA officials said it was decided today to hold Jerrett out as a precaution. Miller had said at his news conference Tuesday that he expected Jerrett would play tonight but also indicated UA wanted to make sure the injury would not progress into a stress fracture or stress reaction.

“We’ve caught it at the very, very beginning and with someone of his size, we want to make sure we’re responsible and do all the tests necessary, which we’ve done,” Miller said Tuesday. “And he’s fine. So every day that he takes off we’re being more precautionary at the beginning. Big-picture-wise, that will help us moving forward. I’m hoping he’ll be able to play (against Stanford). If that changes, something will have happened between now and the game.”

Jerrett has been UA’s top post reserve, averaging 20.0 minutes per game in conference play, and could have been needed against Stanford’s strong-shooting big men. Jerrett is averaging 3.3 points and 4.4 rebounds, and has a team-high 14 blocks in conference games. In all games, Jerrett is averaging 4.8 points and 4.0 rebounds this season.

A McDonalds high school All-American last spring, Jerrett has played in all 21 of the Wildcats’ previous games with two starts.
