The Vikings made official the signings of four players on Monday, including two newcomers in quarterback Sean Mannion and receiver Jordan Taylor. All four inked one-year contracts, according to league sources.

Taylor (6-5, 210 pounds) easily becomes the biggest receiver on the Vikings roster by three inches. The fifth-year pro played sparingly for the Denver Broncos while Gary Kubiak was head coach and then personnel advisor, so the Vikings know what they're getting. He missed the 2018 season following hip surgery.

Taylor, 27, went undrafted in 2015 out of Rice.

Mannion fills the void left by backup quarterback Trevor Siemian, who left in free agency to sign with the Jets. Mannion, a 2015 third-round pick by the Rams, is familiar with the Vikings' new offensive system under Kevin Stefanski and Gary Kubiak, having practiced Sean McVay's adopted influences (from Mike Shanahan) in L.A. (Kubiak and Shanahan go way back.)

Safety Anthony Harris and tackle Rashod Hill signed their one-year restricted free-agent tenders. Harris, a starting safety, was given the second-round tender worth $3.095 million. Hill, a key reserve with 17 starts in two seasons, signed an original-round tender for $2.025 million. The deadline for restricted free agents to sign offer sheets is Friday.

The Vikings now have 67 of 90 roster spots filled ahead of next week's NFL Draft and ensuing college free agency.
