The end of the first week of USC’s spring practices ended with a rather formal celebration.

Jack Sears, who is competing to become the Trojans’ starting quarterback, missed Friday’s on-campus practice because he was a groomsman in the wedding of his teammate and roommate, Andrew Vorhees.

Coach Clay Helton, who previously moved the practice from Saturday morning to Friday afternoon out of concerns over forecasts of weekend rain, gave the rest of the team enough time to celebrate with Vorhees, a sophomore offensive lineman from near Fresno who decided to get married in town.

“I’m going to shower up and go over to the wedding,” Helton told reporters after practice.

Helton, having already declared that he won’t name a quarterback until the fall, didn’t have much to say when asked whether he saw anything from Matt Fink, Sears’ primary competitor for the job this spring, when Fink received all of the first-team reps Friday.

“One thing I took away is how important it’s going to be for all of our quarterbacks just to be able to get live reps,” Helton said. “That’s when things come to life and you get to see where you’re at. Some (things are) good, some we need to fix. But I took away that the more live reps you give him and the rest of the quarterbacks, it’s going to be important to see them in that setting.”

The Trojans now will break for a week, in coordination with the school’s spring break, and Helton sent them away with a message.

Apparently upset with some post-play bickering between the offensive and defensive players, Helton said he called the team together to remind them to focus on the next play, and not to focus on trash-talking about the previous play. Helton, in general, expressed satisfaction with the early-spring progress of the defense.

“Usually the defense is always ahead of the offense early in camp, but we’ll see where it’s at,” Helton said. “We have a really good defense, to be honest with you, from a depth standpoint as well as a talent standpoint. We’ll see, at the end of week two or week three, where we’re really at.”

QUICK HITS

Helton said defensive linemen Jake Lichtenstein and Brandon Pili suffered injuries during Friday’s practice, but “should not be significant.” … Helton named Lichtenstein again, when asked to name players who stood out during the first week of spring practices. Helton also named defensive lineman Jay Tufele.
