The Cowboys signed Foster to a future/reserve contract Monday.
Foster signed with Dallas' practice squad Sept. 13 after going unclaimed on waivers and reaching an injury settlement with the Dolphins ahead of the regular season. The wideout spent the entirety of the 2021 regular season on the Cowboys' practice squad and will have an opportunity to carve out a spot on the team's 53-man roster ahead of the 2022 campaign.
