"This is very disappointing but it is something I have been dealing with for almost two years," Guerrier said Wednesday. "I have had pain in that area. Hopefully I will get it fixed and maybe have a chance to come back here on a minor-league deal next year."
Guerrier, 35, said he has been told the tear is in the area near the elbow. Recovery time is six to eight months, according to the pitcher.
"The tear is less than an inch displaced," he said. "(The doctor) said the ligament looked good and everything else looked good. The doctor said typically for someone who is not a pitcher you could let it go. It feels pretty good right now but the doctor said for a pitcher this is something you definitely want to get fixed."
Acquired in the Carlos Marmol trade with the Los Angeles Dodgers on July 2, Guerrier was 4-4 with a 4.01 ERA this season. He had a 2.15 ERA in 15 appearances with the Cubs and is in the last year of a three-year contract.
"The recovery is shorter than Tommy John surgery," Guerrier said. "It will be six to eight months. It kind of depends on the rehab and no setbacks. It will be six months if everything went great, seven to eight months if you had to take some time off."
