http://www.nfl.com/news/story/09000...e-replacements-for-barwin?module=HP_headlines The Houston Texans, who lost defensive end Connor Barwin for the season Sunday with a dislocated ankle, worked out three free-agent defensive ends on Tuesday morning -- Ryan Denney, Adewale Ogunleye and Bobby McCray, the Houston Chronicle reported via Twitter. Denney played eight seasons for the Buffalo Bills but was not re-signed in the offseason. Ogunleye is a 10-year veteran who played for the Chicago Bears for the past six seasons. He sustained a broken leg in December and was not re-signed in the offseason. McCray, a seven-year veteran, was recently released by the New Orleans Saints for the second time this offseason. He started all three of the Saints' playoff victories last season. "We've got to replace Connor for the season now, and anyone that's out there as a free agent is a possibility, so I think all doors are open and we'll continue to look at every possibility," Texans coach Gary Kubiak said at his news conference Monday.
