Former Dallas Cowboy quarterback turned math teacher Jon Kitna, will donate the money he makes backing up quarterback Kyle Orton this Sunday to the high school where he teaches and coaches the football team.

Since retiring from the Cowboys, Kitna, who played for 15 seasons and four different teams, has taught math and coached football at Lincoln High School in his native Tacoma, Wash.

The Cowboys signed the 41-year-old to play as Kyle Orton’s backup if Tony Romo can’t play against the Eagles on Sunday.

The high school football team he coaches finished its season last month at 8-2. Kitna’s son, Jordan, a sophomore, was his starting quarterback.
