Patriots defensive end Ty Warren said on Thursday that he expects to be ready for the start of training camp in July after he had double groin surgery this off-season. Warren went under the knife in January to repair a torn groin muscle on his left side and also had repair work done to the groin on his right side, as well as a procedure to fix a sports hernia injury. "I'm approaching it like I'm going to be ready, and I think I will be," said Warren, who missed three games with the left groin injury last year and was able to gut out four other games, including the final three of the season, at substantially less than 100 percent.
