Tennessee Titans tight end Delanie Walker left Sunday's game against the Baltimore Ravens late in the first half on a cart and will miss the rest of the contest. Walker appeared to catch a ball near midfield, then fumbled and absorbed an open-field hit. After being taken to the locker room for evaluation, the club revealed Walker suffered a concussion. http://www.sportsnetwork.com/merge/tsnform.aspx?c=sportsnetwork&page=nfl/news/news.aspx?id=4736767
