Schlichting has soreness in his right shoulder and is scheduled to receive an MRI on Monday. Schlichting said he's been pitching with what he believes is tendinitis in the shoulder all season but had previously been unaffected by it and felt no need to mention the condition to the team.
On Saturday, when Schlichting allowed two runs and recorded two outs on 16 pitches in his only appearance since being recalled on Aug. 20, something was different.
"Usually once I get loose, I don't feel anything," Schlichting said. "I didn't want to make a big deal out of it, until last night. Usually, once I'm in the game, my adrenaline's going. ... Last night it was almost hurting every pitch."
Weaver, who turned 34 Sunday, has been out since Aug. 3 because of tendinitis in his left knee. He was to make two rehab appearances for Class A Inland Empire this week, but those were not considered necessary for him to return.
Weaver said he has felt ready to go for some time.
"Absolutely. I'd say since probably two bullpens ago, the last simulated game went really good [on Wednesday]," he said. "I'm ready to go and hopefully I hold up the rest of the way."
Weaver is 5-1 with a 5.35 ERA in 37 innings this season. Schlichting is 1-0 with a 3.57 ERA in 22 2/3 innings.
