Connor Halliday’s retirement from football was nearly as brief as his stint with the Washington Redskins, the team that signed him as undrafted free agent out of Washington State last spring. Halliday boarded a flight home from Kansas City on Tuesday after a tryout with the Chiefs. He worked out for the team on Tuesday morning before meeting with coach Andy Reid and his staff. The team cannot sign Halliday until after the preseason is over in two weeks, at which point Halliday hopes the team will sign him to its practice squad.
