Input: Consider Input: Question: What was the name of the head coach of the team that Lockett played against on November 5th? Passage:He had hoped to redshirt during the 2011 season, which was his freshman year, so that he could add size. He played in 2011 as a true freshman and got off to a modest start. Lockett only recorded four receptions for 50 yards, three rushes for nine yards, one kickoff return for ten yards, and two punt returns for a total of 13 yards in his first five games through October 8. Things started to turn around on October 15 when he posted a 100-yard return of a kickoff for a touchdown against Texas Tech. Over the ensuing weeks, he earned numerous Big 12 Conference honors for the 2011 team, including becoming a two-time Big 12 Special Teams Player of the Week. His first Player of the Week recognition came on October 24 after he produced a 251-yard all-purpose yards performance on October 22 against Kansas in the Governor's Cup that included posting a 97-yard kickoff return touchdown while becoming the first player in school history to return kickoffs for touchdowns in consecutive games and having a career-high five-reception 110-yard receiving day. His other Player of the Week recognition that season came on November 7 after a 315-yard all-purpose yard November 5 game against Oklahoma State that included an 80-yard kickoff return and three rushes for 84 yards as well as three receptions for 32 yards and a touchdown. Due to what was at first an undisclosed injury, he did not play in the final three games of Kansas State's regular season. Later, the injury was determined to be a lacerated kidney. In the four games before the injury, he had at least three receptions and 125 all-purpose yards in each game.
