With starting nose tackle Linval Joseph still sidelined with a toe injury, the Vikings on Tuesday worked out a pair of free-agent nose tackles, including Phil Taylor, a former first-round draft pick of the Browns.

A source told our Mark Craig that the team has not decided whether to sign Taylor, 27, who was last listed as 6-foot-3 and 335 pounds.

The Browns selected Taylor 21st overall in 2011. He spent four seasons with the Browns, playing 44 games and recording 109 tackles and seven sacks before they released him after the preseason. He has since had tryouts with the Ravens and Steelers but did not sign with either team.

The Vikings also worked out nose tackle Euclid Cummings, according to ESPN 1500. He most recently played with the CFL's Toronto Argonauts.

Joseph has missed the past two games because of a toe injury and missed practice again today. Three-technique Sharrif Floyd has started in his place. The Vikings also have Tom Johnson and Kenrick Ellis at defensive tackle.
