There's not much Chad Greenway hasn't seen or done through the course of 10 NFL seasons.

The list grew smaller Sunday when the weakside linebacker was called on to play snaps at middle linebacker for the first time in Minnesota's 21-18 overtime victory over St. Louis.

Greenway was already filling in for Eric Kendricks as one of two linebackers in the Vikings nickel defense, but an ankle injury midway through the fourth quarter to Audie Cole, who replaced Kendricks in base defense, caused Minnesota to move Greenway to MLB and bring in Brandon Watts at WLB.

The Vikings defense limited the Rams to three points in the second half, forced six punts and a missed field goal on their eight possessions after halftime. Four of the eight possessions were limited to three plays before St. Louis had to punt.

Greenway was credited with 10 tackles by press box statisticians, including a tackle for loss. He played all 74 defensive snaps and has been selected for the Bridgestone Performance of the Week.

The Vikings (6-2) have moved into a tie for first place in the NFC North with the Packers, who will visit Minnesota at 3:25 p.m. (CT) on Nov. 22. Minnesota is also tied with Seattle for the stingiest defense in the NFL (17.5 points per game).

The Vikings visit the Oakland Raiders (4-4) at 3:05 p.m. (CT) Sunday.
