Phillips left Sunday's practice session due to an ankle injury, Pat Leonard of the New York Daily News reports.
Phillips sustained the injury during 11-on-11 drills Sunday, and he was held out of Monday's practice session. The rookie third-round pick out of Kentucky is set to operate as the Giants' third corner alongside starters Cor'Dale Flott (quadriceps) and Deonte Banks. Tre Herndon took Phillips' place in drills Monday, and the former would be in line to see more first-team snaps should the latter be unable to suit up for Saturday's preseason game against the Texans.
