Former sixth-round pick B.J. Dubose suffered an ACL injury during the second practice session of OTAs. On Tuesday, the Vikings waived B.J. Dubose and replaced him with former Bears and Packers DT Bruce Gaston.
Dubose was waived with the injury designation and could be signed to injured reserve after clearing waivers.
The 6-2, 310-pound Gaston played college ball at Purdue. He was signed by Arizona as a UDFA in 2014 and spent his rookie season bouncing from Arizona to New England to Miami to Arizona again to Green Bay, spending short stints on the active roster in Arizona, Miami and Green Bay.
