BOSTON -- Curt Schilling will miss his next start on Monday against the White Sox with a mild strain in his right side.
The Red Sox ace, who is tied with Josh Beckett for the team lead in wins with 14, felt his latissimus stiffen while warming up for his last start against Oakland on Wednesday.
"Schill, when he was warming up in Oakland, felt his lat," Red Sox manager Terry Francona announced after Friday's 2-1 victory over the Blue Jays. "But because he was hot, you don't feel something like that until you're done. He showed up [Thursday] very, very stiff. He's got a Grade 1 strain. He's going to miss a turn."
Francona said Schilling's replacement will be named based on how the beleaguered pitching staff gets through the weekend.
On Wednesday, Schilling became the 14th pitcher in Major League history to reach 3,000 strikeouts. He would fan three more batters on the afternoon, but was handed a loss when allowed six runs on 11 hits over 5 1/3 innings.
Although he's 39, he can still bring the heat.
"I always felt like it was something I could always get," Schilling said. "I always felt like it could get me a huge advantage in a game, the ability to go after a strikeout in a strikeout situation and get it. I've always thrived on that."
Kevin Jarvis will make his Red Sox debut Saturday afternoon against Toronto, and Josh Beckett will make his normal start on Sunday. Kason Gabbard is scheduled to start Tuesday's game against the White Sox.
