Minnesota Vikings Hall of Fame defensive end Chris Doleman is undergoing surgery in Atlanta to remove a brain tumor.
The Star Tribune reports that well-wishers have flocked to Twitter to express support for Doleman, who played for the Vikings from 1985 to 1993.
He then moved on to spend two years with the Falcons, three with the 49ers and one final season with the Vikings in 1999. Doleman had 150 ½ career sacks, 22 of which came during the 1989 season.
