Senior guard Jamie Wu, perhaps the Maryland Terrapins' best offensive lineman, will receive an epidural block injection today in an attempt to ease intense back pain that has caused him to miss practice recently.

Coach Ron Vanderlinden said Wu, who has three bulging disks, could be affected for the rest of this season.

"It's kind of similar to the Cal Ripken situation," Vanderlinden said, alluding to the back pain that has twice forced the Baltimore Orioles third baseman on to the disabled list this season. "We're going to give [Wu] a slight injection to try and calm it down."

Vanderlinden said Wu will rest until Monday, and then be re-evaluated. Wu underwent an MRI exam this week, but Vanderlinden said the result "didn't show anything that was alarming."

Wu is one of four returning offensive line starters for the Terrapins, but his backup at right guard, redshirt sophomore Chris Snader, has appeared in only one game during his career.

Meanwhile, starting quarterback Randall Jones has returned to practice after suffering from a sore arm, but Vanderlinden said redshirt freshman Calvin McCall is farther along now than Jones.

Jones "is a bit rusty," Vanderlinden said.

Jones, a sophomore, and McCall took snaps with the first team yesterday at practice, with freshman Latrez Harrison also getting some work with the group. Vanderlinden remained noncommittal about the starting position.

"It's way too early for us to come to any kind of conclusions," he said. "We're evaluating it daily. We're orchestrating snaps in practice. But we're not going to rush with these kinds of decisions."
