CHICAGO - Prior to tonight's game at Boston, the Chicago White Sox placed right-handed pitcher Gavin Floyd on the 15-day disabled list (retroactive to July 8) with right elbow tendinitis, returned right-hander Philip Humber from his injury rehabilitation assignment at Class AA Birmingham and reinstated him from the disabled list.

Humber, 29, has been on the disabled list since June 22 (retroactive to June 17) with a right elbow flexor strain.  He went 1-1 with a 3.65 ERA (5 ER/12.1 IP) in three rehabilitation starts between Class AAA Charlotte (two) and Birmingham (one), allowing one run on two hits over 6.0 IP in his last outing for the Barons on July 12 vs. Tennessee.

Humber has gone 3-4 with a 6.01 ERA (45 ER/67.1 IP) and 63 strikeouts in 12 starts for the White Sox this season.

Floyd, 29, is 7-8 with a 4.54 ERA (52 ER/103.0 IP) and 91 strikeouts in 17 starts this season.  He is 3-1 with a 1.37 ERA (4 ER/26.1 IP) over his last four starts and threw 7.2 scoreless IP in his last outing on July 7 vs. Toronto.

This is Floyd's first trip to the disabled list in his 11-year professional career.
