Vanderbilt football coach Derek Mason has signed a three-year contract extension with a raise and increased recruiting budget, athletics director David Williams confirmed Tuesday.

Per Mason's request, multiple assistant coaches also received contract extensions and raises, including offensive coordinator Andy Ludwig.

After coaching three seasons, Mason's contract was extended back to its original terms of five years with an option of a sixth.

Williams did not provide Mason's specific pay, but he said it was a raise above his previous compensation, which included a base salary of about $2.5 million in 2015, according to the most recently available tax records.
