The Raiders have been busy stacking up veteran free agents, and added another pair Saturday.
The Eagles made no apparent effort to retain Agholor, their 2015 first-rounder. He missed five games last year, and caught 39 passes for 363 yards and three touchdowns.
He was No. 97 on PFT’s Top 100 Free Agent list.
The 30-year-old Kush spent last year with the Browns, starting seven games, and was released in February.
