Jaguars coach Jack Del Rio was caught off guard on Friday morning when he was told his starting quarterback, Byron Leftwich, was favoring a sore left ankle. He didn't practice today. He'll get an MRI this afternoon. He came in today and it was swollen and sore, Del Rio said following Friday's practice. We'll see what the MRI results say and make a decision leading up to the game, Del Rio said of Leftwich. He practiced (Thursday) and walked out of here. He just woke up this morning sore. We hope it'll settle down and be OK. http://www.jaguars.com/story/5559.asp Looks like DG has a good chance of starting. If this is the case, Texans chance of winning dramatically increases.
