TCU coach Gary Patterson doesn't expect anything too serious when quarterback Casey Pachall's MRI test results come back Wednesday. "We don't think it's a big deal," Patterson said after Wednesday's morning scrimmage at Amon G. Catter Stadium. "I don’t expect to see anything." Pachall has missed the last three practices, including Wednesday's scrimmage, with shoulder soreness. He was suited out the last two days but did not throw, according to Patterson. Pachall told Patterson the soreness is from a hit he sustained during a practice, but Patterson isn't so sure. "I can’t find anywhere on film when he was hit, but he says he was," Patterson said.
