Quarterback Mike Hartline will have surgery to repair torn cartilage on his injured knee, effectively ending his regular season.Hartline will miss the final two regular-season games, but head coach Rich Brooks is hopeful that he can return for bowl practice and possibly the game.”Under the quickness and speed of the game (the knee) responded a little differently than it did in practice,” Brooks said.Hartline, who started UK’s first five games before getting injured in the South Carolina game, played sparingly in UK’s bowl eligibility clinching victory. He was 2-for-6 for 10 yards with an interception before true freshman Morgan Newton took over the reins for good in the second half. “When the game starts flying as fast as it does in the SEC and you try to plan and move, it just was not functioning (properly),” Brooks said.Hartline, a two-year starter, will finish the regular season 79-of-133 for 802 yards with six touchdowns and seven interceptions.
