The Raiders locked up five of their own on Monday afternoon.
LB Shilique Calhoun, LB/DE James Cowser, S Erik Harris, G/T Denver Kirkland and K Giorgio Tavecchio all re-signed as exclusive right free agents.
Calhoun, a 2016 third-round pick, has had a bump tenure with the Raiders. Prior to the start of the 2017, Calhoun was waived and signed to the practice squad the next day.

Tavecchio, who had spent several summers with the Raiders, finally got his chance this past season when longtime Raiders kicker Sebastian Janikowski suffered an injury. He made 33 of 34 extra points and connnected on 16 of his 21 field goal attempts.
The Raiders also announced that they have released long snapper Andrew East.
