The Raiders designated Bech (forearm) for return from injured reserve Monday.
The transaction opens up a 21-day window wherein Bech can practice with the team while the Raiders evaluate him for a potential return to the 53-man roster. Before fracturing his left forearm in a Week 3 win over the Saints, Bech had recorded five receptions for 48 yards and a touchdown on six targets while serving as the Raiders' No. 3 wideout behind Tre Tucker and Jalen Nailor.
