Jones, a rising junior, was expected to compete for the No. 2 cornerback role opposite Nick VanHoose. He received a medical redshirt last year after undergoing season-ending knee surgery. Jones tore his ACL last August while defending a pass in the second quarter of Northwestern's game against Cal.
Though he didn't practice in spring, Jones was expected to contribute this season. Now, an additional injury sustained this spring has forced his career to an early end, according to Fitzgerald.
It's a bad loss for NU, but one that it can shoulder. Rising sophomore Matthew Harris was strong in his relief of Jones, and Dwight White will provide solid competition for the nickel position. Redshirt freshman Keith Watkins, one of the team's most improved players this offseason, bolsters cornerback depth as well.
