Manager Robin Ventura said after Wednesday's game that the move was coming, with Danks scheduled to start Friday's series opener against the Miami Marlins.
The left-hander occupies the roster spot vacated when Donnie Veal was optioned to Triple-A Charlotte after Wednesday's game.
It was Danks' first appearance in a major league game since May 19 of last year, when he pitched 6 1/3 innings in a victory over the Cubs at Wrigley Field. He pitched 6 innings Friday night, giving up 4 hits and 3 runs while striking out five. The White Sox won in 11 innings.
Danks had shoulder surgery in August, and even though he participated in spring training, including appearances in Cactus League games, he opened the season on the disabled list. After a stint in extended spring training, Danks had four minor league rehab starts, the last three of which were with Charlotte.
The 28-year-old Danks has a career 58-60 record with a 4.12 ERA over 159 starts, all with the White Sox.
