Duke head football coach David Cutcliffe announced that rising redshirt senior quarterback Thomas Sirk suffered a ruptured left Achilles tendon on Tuesday morning during a team conditioning session. Sirk is scheduled to undergo surgery on Wednesday morning.

The surgical procedure will be performed by Dr. Claude T. Moorman III, Duke’s head team physician and the executive director of the Duke Sports Science Institute.

No timetable has been set for Sirk’s return. Sirk missed the 2013 campaign after suffering a ruptured right Achilles tendon in April of that year.
