Chaparral running back Emerson Carrethers is expected to miss his senior season after tearing his anterior cruciate ligament in a scrimmage last week, coach Dave Huffine said.
Carrethers was the team's top rusher in 2012, carrying the ball 108 times for 869 yards and four touchdowns. The injury was non-contact, occurring on an open-field cut.
"It's sad because he's such an unbelievable kid and was ready to have a breakout season," Huffine said.
Sunrise Mountain transfer Elijah Castro is expected to get many of the carries, while Malcolm Thomas and Justin Paniagua will also see time in the backfield.
Chaparral tight end Trevor Wood sat out the scrimmage as a precaution but will be good to go in Friday's season opener against Saguaro. Wood is a highly-rated recruit but injuries have kept him from making a big impact during his high school career. He missed almost all of last season with a shoulder injury.
He will play defensive end in addition to offense this year. Huffine said Wood is ready to live up to the expectations thrust upon him.
"He feels as if there was a lot of hype around him because he has the ability to do these great things, but he knows he hasn’t (produced) in a high school football game to warrant that," Huffine said. "He wants to prove he’s worth every bit of it."
