The Texas Rangers confirmed Monday that closer Frank Francisco is back on the 15-day disabled list for a third time this season.
Francisco, 29, is suffering from pneumonia.
"He was available [Saturday] out of the bullpen, and then it just hit him too hard," Rangers manager Ron Washington said.
The move is retroactive to July 11 because Francisco hasn't pitched since July 10.
He is eligible to be activated Sunday.
"We didn't want him around the rest of those guys," Washington said.
Francisco is 2-1 with a 2.28 earned-run average in 28 relief appearances and 15 saves in 17 opportunities this season.
The Dominican right-hander was sidelined from May 7-22 with right biceps tendinitis and from June 4-20 with right shoulder tendinitis.
Francisco has compiled an 11-9 record with a 3.53 ERA and 20 saves in 198 relief appearances since he broke into the majors with the Rangers on May 14, 2004.
To replace him on the roster, Texas recalled right-hander Willie Eyre from the triple-A Oklahoma City RedHawks.
