Washington was one of the Chiefs' 1972 draft picks. He was later traded to the Oilers (or released by the Chiefs?) in time to play in Houston's 1973 season-opener.

Anyone know the exact date (or, at least the month) when he was traded and/or let go by the Chiefs? Did Washington play any preseason games for KC? I'm inquiring to help narrow down the date of a KC Chiefs autographed football.

Thanks in advance
