ARLINGTON, Texas - New Orleans Saints cornerback Jabari Greer left Sunday's game at Dallas because of a concussion.

It wasn't immediately clear when and how Greer got the concussion that was announced early in the second half. He had two interceptions the previous week for New Orleans in a win over Tampa Bay.

Dallas linebacker and sacks leader DeMarcus Ware was on the sideline in the fourth quarter with a right shoulder strain. Ware has been limited in practice in recent weeks by a right elbow problem.

Cowboys starting linebacker Ernie Sims, who left last week's win over Pittsburgh with a concussion, came out of Sunday's game in the first half because of what the team said was dizziness.
