T.Y. McGill posted 3½ sacks in the Vikings' first two preseason games. He sprained his right ankle in their third preseason game in Denver on Saturday night.
On Monday, as the Vikings began the process of reducing their active roster to 53 players before Tuesday's 3 p.m. deadline, McGill became one of the first players to lose his spot on the team.
The Vikings put the journeyman defensive lineman on injured reserve on Monday, ending his bid to make their roster out of training camp.
McGill's ankle injury is expected to keep him out for one to two weeks, a source said on Sunday, but he will have to get a second opinion on his ankle to determine whether he could be released after receiving an injury settlement or remain on the Vikings' injured reserve list for the season.
